China Building Large Radio Telescope For Space Observation
"China Building Large Radio Telescope For Space Observation
by Staff Writers
Shanghai (XNA) Jan 04, 2010
Construction of a 65-meter-diameter radio telescope started Tuesday in Shanghai, an official from one of funders said Wednesday. The telescope, a form of directional radio antenna used in radio astronomy, will be used in tracking and collecting data from satellites and space probes including Chinese astronomical projects like Chang'e lunar probe, YH-1 Mars exploration and other deep space explorations, said Zhan Wenlong, deputy dean of the Chinese Academy of Sciences (CAS).

The facility is also capable of receiving data for Jupiter and Saturn exploration, said Hong Xiaoyu, head of Shanghai Astronomical Observation, which will run the project after it is expected to be fully completed in 2015.
The 200-million-yuan (29.3 million U.S. dollars) project, funded by CAS, Shanghai Municipal Government and Chinese lunar probe project, will have a bowl-like surface composed by 1,008 panels as large as eight basketball courts in total area, said Hong.
The antenna structure of the telescope is scheduled to be finished by September 2012 and the facility is set to be used for tracking and locating missions during China's lunar probe program from 2013 to 2014.
China's Very Long Baseline Interferometry (VLBI), a type of astronomical interferometry used in radio astronomy would go up by 42 percent in terms of its sensitivity if the telescope replaces the current 25-meter one in Shanghai.
VLBI, composed of four telescopes in Shanghai, Beijing, Kunming, Urumqi and the data center in Shanghai was used for tracking and locating purposes during the first phase of China's lunar probe program."

China begins 26th Antarctica season with a team of 251 scientists
Chinese scientists have set off from Shanghai for their 26th research mission to the Antarctic. The Snow Dragon, China's main research ship in the polar region, has gone through a series of maintenance and technical readjustments, according to Global Times.
Chinas impressive icebreaker Xue Long or Snow Dragon
The new Antarctic season will last six months and cover a distance of more than 30,000 miles, the longest mission to date.
One of the main objectives of this season is collecting remains of meteorites and astronomic observation. The Xue Long carries a record 252 scientists and technicians including for the first time several from Taiwan. Russian and Australian scientists have also been invited.
A team of scientists will remain at the Zhongshan base in the bay of Prydz from where it will cover 400 kilometres to the Grove mountain range to collect as many meteorites as possible. China has the worlds third largest collection of meteorites.
Another team will land a the Kunlun base which is situated 7.3 kilometres southwest from the Argus summit, the highest point in Antarctica with 4,093 metres above sea level. The purpose is to install astronomic surveying equipment.
Two other teams will explore inland Antarctica.
Chinas first Antarctic base, Changcheng (Great Wall) was established in 1985 south of King George island, and the second Zhongshan in 1989 south of the Prydz bay, in the Mirror peninsula east of the Larsemann hills.
Kunlun is the first Chinese base in continental Antarctica.
In the last 25 years China has completed 4,000 trips to the Southern Pole, according to the Chinese Institute of Polar Research.
Xue Long is expected back in Shanghai in late April 2010.
MV Xue Long, built originally as a polar cargo ship by Kherson Shipyard, Ukraine, on March 25, 1993, became the only research ice-breaker in China after elementary modification in 1994, for the Arctic and Antarctic regions. It is the re-supply vessel and the scientific research platform of the Chinese Arctic and Antarctic research expeditions. The vessel is 167 meters long and 22.6 meters beam, with the full-loaded draft of 9 meters, the full-loaded displacement of 21,250 tons, and the cruising radius of 12,000 nautical miles.
It is an A2-class ice-breaker with capability of breaking ice 1.2m (including 0.2m thick snow) at a sailing speed of 2 knots and can sail with the maximum speed of 17.9 knots, and also sail even during the weather of gale with more than 12 B scale.
The vessel has a data processing centre and seven laboratories with total area of 200 square meters and basic operating equipment on board of this vessel, including a low temperature sample storehouse, a low temperature cultivation room, a clean laboratory, a marine biological laboratory, a marine chemical laboratory, a geological laboratory, and a CTD winch, a biological winch, a geological laboratory, and a hallow-section device of EK-500 model.
Besides, 3 operating boats and a helicopter are equipped for the transportation and research purposes in the Arctic and Antarctic regions."

QINGDAO, July 25 (Xinhua) -- A group of Chinese researchers are cultivating human cells to make artificial corneas in a laboratory, bringing hope to some 5 million victims of corneal blindness in China.
The research team from the Ocean University of China (OUC) was expected to produce a complete cornea and begin clinical trials in three to five years, said Fan Tingjun, deputy dean of the College of Marine Life Science at the OUC.
An artificial cornea, each expected to cost 10,000 to 20,000 yuan (1,475 to 2,950 U.S. dollars), would provide an alternative for those patients anxiously awaiting donated corneas for transplant surgery, Fan said.
"Chinese doctors can only perform corneal transplant operations, currently the only cure for corneal blindness, on 3,000 to 4,000 people every year due to a lack of donors," he said.
The cornea, a vulnerable shield protecting the eye and also playing a key role in creating vision, consists of three main layers -- the endothelium, stroma and epithelium.
The research team had made a major breakthrough by using tissue-engineering technologies to create a tissue similar to the endothelium, an innermost, single layer of cells essential to keeping the cornea clear, Fan said.
The creation of endothelium remained a key barrier in the global study of artificial corneas because the cells of the endothelium could not regenerate, which added great difficulties to cell cultures, said Fan, whose team started their research in 2002.
Before 2002, many researchers throughout the world resorted to the cancer gene to stimulate the growth of endothelial cells during the culture.
"So their achievements couldn't apply to clinical therapies, but only for further research," Fan said.
After nine years of trial and error, the team successfully cultivated a large quantity of normal human endothelial cells with the assistance of supports made of human amnion.
An evaluation panel of top ophthalmologists described their breakthrough as "building up the first endothelial cell line in the world without risks of causing tumors", as written on the achievement evaluation certificate issued by the State Science and Technology Commission.
The researchers have transplanted the artificial endothelium to a rabbit, which maintained the transparency of its cornea for more than a year.
Now the team is working on the production of stroma, which accounts for 90 percent of the thickness of the cornea and serves as a bridge between the endothelium and epithelium, the outmost layer of the cornea to block outside dust and bacteria from reaching the eye, as well as absorb oxygen and cell nutrients from tears.
Although some of Fan's foreign counterparts have produced artificial stroma similar to that found in the human eye, these have not functioned well when transplanted in animals, Fan said.
"We have chosen proper seed cells and supports made of composite materials to produce stroma. Now, we're performing adjustments of the supports' structure and function and hopefully will be finished in three to five years," Fan said, adding that the production of epithelium, which was comparatively easier, had been accomplished successfully years ago.
The researchers are working with the Qingdao Yuming Biotechnologies Co., Ltd to produce 150,000 to 200,000 pieces of endothelium every year to benefit more than 800,000 Chinese who became blind after their endothelium was damaged.
"The mass production of complete corneas will be launched after the artificial cornea passes the clinical trials," Fan said.

Scientists have created speakers made from carbon nanotube sheets, with properties that make them ideal for submarine sonar to probe the ocean depths and make subs invisible to enemies.
These "nanotube speakers" are a fraction of the width of a human hair can both generate sound and cancel out noise.
Ali Aliev and colleagues explain that thin films of nanotubes can generate sound waves via a thermoacoustic effect.
Every time that an electrical pulse passes through the microscopic layer of carbon tubes, the air around them heats up and creates a sound wave.
Chinese scientists first discovered that effect in 2008, and applied it in building flexible speakers.
In a remarkable demonstration, which made its way onto YouTube, the Chinese nanoscientists stuck a sheet of nanotubes onto the side of a flag, and attached it to an mp3 player.
They used the nanotube-coated flag to play a song while it flapped in the breeze. But they did not test its ability to operate under water.
Aliev's group took that step, showing that nanotube sheets produce the kind of low-frequency sound waves that enable sonar to determine the location, depth, and speed of underwater objects.
They also verified that the speakers can be tuned to specific frequencies to cancel out noise, such as the sound of a submarine moving through the depths.
The study has been published in ACS' Nano Letters, a monthly journal. (ANI)

LAMOST Progress : All the MB (spherical primary) segments are in place on June 19, 2008
China's LAMOST telescope in Xinglong, China
Heidi Newberg, Astronomy, Supernova, Dark energy, Careers Q&A, Naturejobs
"Published in Nature 466, 279 (7 July 2010) | 10.1038/nj7303-279a
Virginia Gewin
Heidi Newberg, a physicist and astronomer at Rensselaer Polytechnic Institute in Troy, New York, has won a National Science Foundation grant to create the first partnership between a US team and a Chinese-led astronomy project.
Were you always planning to become an astronomer?
No. I went to graduate school in the physics department at the University of California, Berkeley, but I didn't know what I wanted to study. After my first year, I got a job with the Berkeley Automated Supernova Search, analysing images. I had no background in astronomy and didn't even know what supernovae were, but it sounded interesting because it was unexplored and would make use of my analytical thinking skills. Later, I began working on the distant-supernovae search, which ultimately became Berkeley's Supernova Cosmology Project. The distant-supernovae search did not achieve success until after I had left and started my postdoc at Fermilab in Batavia, Illinois, but later versions of the search benefited from the wrong turns we made starting out. Eventually the data were used in the discovery that the Universe is accelerating. Those findings led to the idea of 'dark energy'. My career has been shaped by a theme although projects can seem bleak at the start, continuing to work on them can lead to an important result.
How were supernovae found?
First we had to work out what was going wrong. We couldn't have done it without constant funding for the supernova group from the US Department of Energy at Lawrence Berkeley National Laboratory there has to be a way to keep going long enough to get things to work. You need to learn from your mistakes. One thing we learned is that to find a supernova, you can't record images of the sky once, and come back the next year and expect things to be the same. Too many things in the sky change to be able to tell which objects are supernovae and which aren't. We learned to capture an image of the sky before and after a full Moon to get the best spectra for finding supernovae.
Describe how an early achievement helped to chart your career course.
As a graduate student, I had the task of redesigning a filter wheel that was part of an instrument for the Anglo-Australian Telescope, one of the first Southern Hemisphere telescopes to offer high-resolution and computer-controlled spectrographs. I hadn't worked on hardware. I didn't know anything about optics or filter wheels, but I talked to the engineers and got answers. It came together, but the challenges showed me that with projects that push the envelope of what is known and possible, you are going to have to learn new things.
How did you forge the partnership with China?
It came together from both sides. I had been analysing data from the Sloan Digital Sky Survey in Sunspot, New Mexico, but data collection ended in 2008. So I was looking for a new project. I was interested in working on the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) in Xinglong, China, because I wanted to continue with a galactic evolution project that I was exploring using Sloan data. But I needed data at a bigger scale, taking measurements on millions of stars. Using LAMOST I will have that, because it can take 4,000 spectra at once. I was also approached by the Chinese delegates as they talked to people involved in building Sloan, to learn how to make LAMOST successful. They contacted me because they wanted people to help them build the software.
What are the challenges in being a member of the first US team to join a Chinese-led astronomy project?
The Chinese structure for science is not similar to US or European structures. In China, individuals rather than teams are in charge. In US and European collaborations, committees are formed with representatives who have voting rights. It is like a democracy. With such different structures, it has been a challenge to define everyone's objectives, responsibilities and rights. The US National Science Foundation expects us to spell out the details in a proposal which might be funded up to a year later, whereas the Chinese organizations want to start working together and see how the relationship evolves, so there is a mismatch.
So have your goals changed?
No. No matter what the top layers look like, the scientists' expectations are similar. The challenge is getting the big organizations to recognize each other's systems rather than getting individuals to work together. I'll travel to China two to four times a year to make this programme a success.
What is your motto?
For the longest time, I told myself, I can do anything. When I turned 40, I realized that there are some things I simply can't do. Yet my motto got me pretty far before I figured that out."

a French-Chinese collaboration
The Space multi-band Variable Object Monitor (SVOM) is a proposed Chinese astronomical satellite, dedicated to the detection, localization and measurement of gamma-ray bursts (GRBs) on a cosmological scale. An efficient algorithm is developed for the purpose of onboard star extraction from the CCD images obtained with the Visible Telescope (VT) onboard the SVOM. The CCD pixel coordinates of the reference stars will be used to refine the astronomical position of the satellite, which will facilitate triggering rapid ground-based follow-up observations of the GRBs. In this algorithm, the image is divided into a number of grid cells and the global pixel-value maximum within each cell is taken as the first-guess position of a bright star. The correct center position of a star is then computed using a simple iterative method. Applying two additional strategies, i.e., scanning the image only by even (or odd) lines or in a black-white chess board mode, we propose to further reduce the time to extract the stars. To examine the efficiency of the above algorithms, we applied them to the experimental images obtained with a ground-based telescope. We find that the accuracy of the astronomical positioning achieved by our method is comparable to that derived by using the conventional star-extraction method, while the former needs about 25 times less CPU time than the latter. This will significantly improve the performance of the SVOM VT mission.

Since Richard Feynman's first envisioned the quantum computer in 1982, there have been many studies of potential candidates -- computers that use quantum bits, or qubits, capable of holding an more than one value at a time and computing at speeds far beyond existing silicon-based machines for certain problems. Most of these candidate systems, such as atoms and semiconducting quantum dots, work for quantum computing, but only at very low temperatures.
Now a team of researchers from the Wuhan Institute of Physics and Mathematics, the Chinese Academy of Sciences and the Hefei National Laboratory for Physical Sciences at the Microscale at the University of Science and Technology of China has made a step toward a warmer solution.
As reported in the journal Applied Physics Letters, the team is exploring the capabilities of diamond nitrogen vacancy (NV) materials. In this material, a "molecule" at the heart of an artificially created diamond film consists of a nitrogen atom (present as in impurity amid all those carbon atoms) and a nearby vacancy, a place in the crystal containing no atom at all. These diamond structures offer the possibility of carrying out data storage and quantum computing at room temperature.
One of the challenges of this technology is the difficulty of coupling two of the NV centers in separate nanocrystals of diamond. To make a quantum computer, many diamond-NV centers need to be coupled (made quantum coherent with each other), encoding the information in each, and operations based on their interactions (or couplings) must be undertaken. Mang Feng of the Wuhan Institute of Physics and Mathematics of the Chinese Academy of Sciences and his collaborators present an idea that could lead to a quantum mechanical coupling of these NV centers, called entanglement. This proof of principle is now ready to be extended to multiple operations, which is by no means a simple accumulation of the operations.
"Our research is another step in realizing the potential of the long-envisioned quantum computers with techniques available currently or in the near-future," states Dr. Feng, "Continued advances could stimulate further exploration in condensed matter physics, quantum information science and diamond making technology."
More information: The article, "One-step implementation of multi-qubit conditional phase gating with nitrogen-vacancy centers coupled to a high-Q silica microsphere cavity" by Wan-li Yang et al will appear in the journal Applied Physics Letters.

Diamond Fusion A team of Chinese researchers proposes firing tiny diamond bullets into a chunk of crystal methane to produce nuclear fusion.
A millimeter-sized diamond bullet fired from a linear accelerator could produce nuclear fusion when it collides with a chunk of solid methane, according to a study by Chinese researchers.
Despite the large amount of energy required to accelerate a diamond to 1,000 km/s about 620 miles per second the collision produces a net energy gain, according to the teams simulations.
So far, its just a concept that exists in computer simulations only; no physical studies have been conducted. Only the initial impact and ignition have been studied in detail, and the simulations stop at roughly 50 nanoseconds. So no one should be holding their breath for diamond bullets powering Beijing anytime soon.
The system would work by colliding a 1-cubic-millimeter diamond with crystal DT methane, which has better stopping power than other fusion fuels. Most of the bullets kinetic energy is transformed into a shock wave, producing high pressure and temperatures.
The collisions peak energy is 4 petawatts, at a rate of 1.5 petawatts over 40 nanoseconds. Thats four quadrillion watts. About 80 percent of that energy is wasted in the form of scattered neutrons, but the remaining electrons and radiation are enough to heat things up to fusion temperatures, the paper (PDF) says.
The team says their algorithm is not advanced enough to progress much past the ignition phase. But fusion blogs have been abuzz lately, with one writer speculating that the energy would be even greater if the diamond bullet reaches faster speeds.

ARJ21 jets to be delivered starting from 2011 - People's Daily Online
"ARJ21 jets to be delivered starting from 2011
13:38, July 22, 2010
China's first ARJ21 regional jet is expected to be delivered in 2011, the Commercial Aircraft Corporation of China (COMAC), which develops domestically-made jumbo jets and sells the ARJ21 aircraft, reported during the Farnborough International Air Show on July 21.
ARJ21 is a new type of short-to-medium-range, turbofan-powered regional jet independently developed by China. It has 70 to 100 seats and a maximum range of 2,000 nautical miles. Designed in accordance with international airworthiness standards, the aircraft can meet requirements such as takeoff and landing in plateau or high-temperature airports.
According to COMAC, the ARJ21 regional jet had its first test flight on Nov. 28, 2008 and has entered the airworthiness certification and certificate application stage. Four ARJ21 regional jets have participated in test flights with a cumulative flight time of more than 600 hours. Confirmed overseas and domestic orders and orders of intent have amounted to 240 and the first aircraft is scheduled to be delivered in 2011.
The pre-sale price of the new ARJ21 regional jet is 27 million to 29 million U.S. dollars, giving the ARJ21 regional jet a price advantage over its peers in the international market.
COMAC also noted that China's jumbo jet project will enter the engineering development phase next year. The suppliers for the project have generally been selected after key suppliers of the airframe structure, power units and system devices, materials and standard components were fixed.
Equipment for the C919 jumbo jets will be supplied by 13 international aviation manufacturing enterprises. Meanwhile, over 30 domestic enterprises have passed the preliminary material supply reviews and more than 50 domestic enterprises have been selected as potential standard component suppliers.
COMAC added that the overall technical plan, manufacturing plan and customer service plan for the C919 jumbo jets will be compiled in 2010. The C919 jumbo jets are scheduled to conduct the first test flights in 2014 and be delivered in 2016.

China's 7,000 meter best-in-the-world diving submersible
Ocean floor
China-made submersible has 1,000 m diving capability - People's Daily Online
"China-made submersible has 1,000 m diving capability
15:23, March 11, 2010
Sun Zhihui, CPPCC member and director of State Oceanic Administration, said March 10 in an interview that the home-developed manned submersible, the first of its kind worldwide has been successfully tested in the South China Sea 20 times at depths of 1,109 meters in 2009. The vehicle's maximum operational capability at that depth is 7,000 meters.
As a result, China becomes the world's fifth country after the U.S., Russia, Japan and France to possess the technology of developing a manned submersible with over a 1,000 meter diving capability.
The manned submersible, capable of reaching depths for a distance of 7,000 meters, is the best of its kind in the world. It is capable of exploring 99 percent of the world's ocean floor.

"China builds new manned submersible
Posted on: February 29, 2008 5:07 AM, by Peter Etnoyer
China has a knack for naming their exploration vehicles. They gave the world the Shenzhou (or "divine vessels") to reach outer space and the Taikonauts to fly them. Now China is planning an ocean exploration program 'equally important' to their space endeavours, including plans to build a sub-sea base station and a manned submersible capable of diving to 7000m by year 2010. So, how do you say "sea dragon" in Mandarin?
You can never have too many deep diving manned submersibles. Less than a dozen vessels I know of are capable of working beyond 1000m depth. Between the Chinese submersible, the Alvin, it's replacement, the Russian MIRs, the French Nautile, and the Japanese Shinkai we'll have maybe 6 manned submersibles capable of diving deep enough to explore ~90% of Earth's seafloor as we enter the next decade. We need more.

Shanghai Synchrotron Radiation Facility Opens to Scientific Researchers---Chinese Academy Of Sciences
"Shanghai Synchrotron Radiation Facility Opens to Scientific Researchers
Shanghai Synchrotron Radiation Facility (SSRF), a third-generation of synchrotron radiation light source passes national inspection on January 19 and will be open to home and abroad scientific research, according to Shanghai Institute of Applied Physics, Chinese Academy of Sciences (SINAP).
SSRF is the biggest scientific platform for science research in China up to now. The construction of the project started on Dec 25th, 2004 in Shanghai, and cost 1,200 million yuan (about 176 million U.S. dollars).
The facility consists of three accelerators: a 150Mev electron LINAC, a 180-meter booster that can increase the electron energy from 150MeV to 3.5GeV in 0.5 second, and a 3.5GeV electron storage ring with a perimeter of 432 meters. The project also includes 7 initial beamlines and experimental stations.
The mega experimental platform will then help carry out research on life sciences, medicine and pharmacy, new material, physics, chemistry, petrochemical industry and biotechnology.
[Many] hundreds of scientists and engineers from universities, institutes and industries in domestic and even overseas will be able to use the facility to [perform] research and experiments.
ZHANG Xiaoqiang, Vice Chairman of Chinas National Development and Reform Commission, CAO Jianlin, Vice Minister of Chinas Ministry of Science and Technology, JIANG Mianheng and ZHAN Wenlong, Vice Presidents of the CAS and experts from related areas attended the inspection and acceptance conference held in Shanghai."
"[It] will provide x-ray, infrared and ultraviolet beams of exceptional brightness. These will be used by scientists and engineers for research and development in many fields including biomedical science, medical research, environmental sciences and physical sciences.
What is a Synchrotron Light Source?
A synchrotron light source is a very large machine designed to produce intense beams of light. Millions of times brighter than an X-ray, synchrotron light is generated by using powerful magnets to accelerate electrons that are traveling near the speed of light. Infrared, ultraviolet and X-ray light is shone down beamlines to end stations (small laboratories) where scientists can select different parts of the spectrum to view the microscopic nature of matter, and investigate it at the scale of atoms and molecules. Synchrotron light is an indispensable tool in many research areas including physics, chemistry, materials science and crystallography, and is increasingly being used in medicine, geological and environmental studies, structural genomics and archaeology. Many everyday commodities, from chocolate to cosmetics, drugs, surgical tools, computers and mobile phones, have been developed or improved using synchrotron light."

By Anatoly Zak Science reporter
Chinese engineers are considering a new super-powerful engine for the next generation of space rockets, say officials.
According to Li Tongyu, general manager of the marketing department at the China Academy of Launch Vehicle Technology (CALT), engineers are currently studying a rocket engine capable of generating thrust of 600 tonnes.
If China succeeds in the development of such power, it would increase the nation's capabilities in space by orders of magnitude.
For comparison, China is currently well in the development of its most powerful rocket to date - Long March-5 - that would sport engines with the thrust of 120 tonnes.
"Rockets (with 600-tonne thrust engines) would only be justified for things like sending humans to the Moon, if such projects are approved," Li Tongyu told BBC News.
In March, the official China Daily newspaper disclosed that CALT was studying a super-heavy launch vehicle, which could be used to mount lunar expeditions.
At the time, the newspaper quoted CALT Vice President Liang Xiaohong as saying that the total lift-off thrust of the future heavy launcher would be 3,000 tonnes.
To develop such thrust, the first stage of the proposed rocket would need five 600-tonne engines, possibly distributed between one central stage and four strap-on boosters.
The rocket's architecture would thus be similar to the one adopted for the Long March-5 rocket, but at a considerably grander scale.
Although the expected payload of the future heavy lifter had not been disclosed, available details allow placing it close to the same category with that of the Saturn-5 rocket, which carried US astronauts to the Moon.
In the meantime, the development of the Long March-5 rocket was proceeding well toward its first test launch, currently expected in 2014, Li Tongyu said.
The vehicle's first stage engine had already accumulated more than 10,000 seconds of firing during tests - an important milestone on the way to its certification for real missions.
A full-scale prototype of the Long March 5 rocket would be ready for testing in 2012 and a year later, test firing of fully assembled rocket stages would be conducted.
When operational, Long March-5 is expected to deliver up to 25 tonnes of payload, including space station modules to the low Earth orbit, and up to 14 tonnes to the so-called geostationary transfer orbit, where most communications satellites are released after launch.
At the UK's Farnborough airshow, CALT demonstrated computer-generation videos, showcasing impressive new assembly and launch infrastructure of the Long March-5 rocket.
Newly built facilities will feature a sprawling campus not far from Chinese capital Beijing, where the rocket would be assembled.
The rocket stages would then be shipped to the launch site in the very south of China, where it could take advantage of the Earth rotation to maximise its cargo capabilities.
Along with Earth-orbiting satellites, the Long March-5 is expected to carry Chinese spacecraft into deep space, including unmanned missions to return soil samples from the Moon.

Experimental equipment for ultra-intense ultra-short laser interaction with solid-state target.
Research Highlights-Laser Science Research
"Ultra-Intense Laser Science Research at Shanghai Institute of Optics and Fine Mechanics
Founded in 1964, Shanghai Institute of Optics and Fine Mechanics (SIOM) has been widely recognized as the most important research center in the field of laser science and technology in China. SIOM is one of the about 100 institutes of Chinese Academy of Sciences (CAS), originated for the laser research groups of CAS institutes in Changchun and Beijing, where the first Chinese ruby laser oscillator was demonstrated in 1961.
SIOM has become a comprehensive research institute with the main research fields as high power laser technologies and systems, high-field laser physics using intense and ultra-intense ultrafast lasers, information optics, quantum optics, solid state laser technologies and their applications, laser and optoelectronics materials.
In addition to the earlier achievements in the development of high power laser technologies and facilities, SIOM has developed in recent years the first Chinese multi-kilo-joule laser facility for the basic research of nuclear energy based on the laser driven fusion of the isotopes of hydrogen, together with the relatively compact but much more intense laser facility with the peak power approaching a petawatt (a million billion watt). SIOM is exploring the frontiers of intense and ultra-intense laser science using these facilities and other smaller-scale laser systems with laser pulse durations ranging from a few nanoseconds (billionths of a second) to a few femtoseconds (millionths of a nanosecond), including table-top laser fusion using cluster targets, laser acceleration of electrons and ions, nonlinear propagation of laser beams at relativistic intensity, atomic and molecular physics in intense laser field, high order harmonics and coherent XUV emission generation, attosecond (billionth of a nanosecond) pulse generation and etc. I will highlight some of the recent progress hereafter.
Femtosecond Petawatt Laser Facility
Based on chirped pulse amplification (CPA) scheme, we have developed the femtosecond petawatt Ti:sapphire laser system with a peak power of 0.89 petawatt and a pulse duration of 29.0 femtoseconds [1]. The system consists of a self-mode-locked Ti:sapphire oscillator, a pulse stretcher, four amplifiers and a four-grating pulse compressor. The following three key technologies are essential to this system."
NEWS RELEASE - Media Centre - Shanghai Optics and Fine Mechanics achieves breakthrough in Synthetic aperture laser imaging radar technology - The 4th Asia(dongguan) International Laser Processin Equipment Technology forum&fair (14-16,May 2010)
"Shanghai Optics and Fine Mechanics achieves breakthrough in Synthetic aperture laser imaging radar technology
8th, July News, Shanghai Institute of Optics and Fine Mechanics Space Optical Communications and Technology Key Laboratory testing is supported by major projects. Beginning the research of synthetic aperture laser imaging radar technology since 2008, it has made a breakthrough recently and has achieved the imaging of range and azimuth of a two-dimensional target in the laboratory-scale narrow synthetic aperture laser imaging radar equipment; achieve the complete linking process of synthetic aperture laser radar, optical, opto-electronics and computer processing. This is the world's third report of successful experiments.
Synthetic aperture imaging laser radar (also known as optical SAR) is the only optical means to reach the cm-optical imaging resolution for distant objects. It has a significant prospect in the space field. Features include: 1. Laser active imaging, suitable for all-day use, with high-resolution imaging close to optical visibility, and quick imaging; 2. Radars with a wide range of applications: suitable for space-to-ground observation of super-resolution, space remote-moving target, and ultra-resolution imaging applications.
The United States made the key technological breakthrough of synthetic aperture imaging laser radar in 2002, realized two-dimensional imaging in the laboratory-scale narrow synthetic aperture laser equipment, and (building on this base in 2006) airborne synthetic aperture laser imaging radar prototype that were respectively researched by Raytheon and Northrop Grumman Corporation; thereafter carrying out a variety of field tests and recently expanding the number of applications.
Using a different fiber optics set-up than the experiments in the United States, Shanghai Institute of Optics and Fine Mechanics experimental system used space-optical structures. This resulted in increased experimental difficulties, but would yield more practical results. Due to the differences between the implementation of optical synthetic aperture imaging radar and microwave synthetic aperture radar, the concepts and principles of microwave radar cannot be directly utilized. This makes the study challenging for optical synthetic aperture radar imaging. In the research by Shanghai Institute of Optics and Fine Mechanics Space Optical Communications and Technology Key Laboratory, the institute creatively solved a series of optical science and space-domain obstacles, time-domain optical-scientific issues and statistical optics-scientific issues. Also, the systematic-and-corresponding development of the overall design, optical antennas, and key technologies such as receiver/transmitters optoelectronic systems and image processing has laid a solid foundation for the realization of laboratory-scale synthetic aperture laser imaging radar and a future prototype device.
The outcome of this project serves a leading role in the country. The results of the project's basic research, especially on the issue of space-domain optical-study, have a high degree of innovation; fill gaps in the knowledge of international research; and has quickly received recognition from international colleagues.

China's prototype of the Hard X-ray Modulation Telescope (i.e. HXMT) satellite.
The HXMT has been thoroughly tested. China's first space-based telescope is currently ready and scheduled for launch in 2012 (see Chinese launch schedule).
iTWire - China announces HXMT to be first astronomy satellite
"China announces HXMT to be first astronomy satellite
By William Atkins
The Xinhua News Agency, the official Chinese news agency, has announced that the Chinese space agency is planning a [2012] launch of a space telescope to study x-ray sources such as black holes and neutron stars.
The dedicated astronomy mission, called Hard X-ray Modulation Telescope (HXMT), is being built to perform a collimated hard x-ray (HX) survey of the entire sky with both high spatial resolution and high sensitivity.
The energy range of hard x-rays is about 20 to 200 kiloelectron-Volts (keV). Hard x rays have more energy than soft x rays (SX). For instance, when medical x rays are produced, a metallic sheet is placed in front of the x-ray machine so the soft x rays are filtered out and only the more energetic hard x rays reach the patient. Generally, x rays are a type of electromagnetic radiation with wavelengths of between 10 to 0.1 nanometers (where one nanometer equals one billionth of a meter).
The HXMT mission was selected in 2000 as a project under the Major State Basic Research Program of China. In October 2005, HXMT entered the full design phase and was listed as a possible candidate for the first dedicated astronomy satellite."
"Science Aims
The hard X-ray band is a key waveband for high energy astrophysics studies. Exploring various kinds of black holes is a major frontier of physics and astronomy in the new century. Hard X-rays originate mostly from regions close to black holes and are highly penetrating, and are therefore important tools for studying the physical processes in the extreme conditions such as high matter density, high energy density, high electric-magnetic field, and high gravitational field.
As a hard X-ray telescope with excellent sensitivity and spatial resolution, HXMT will have the following observational targets:
* An all-sky hard X-ray survey. To create a high precision hard X-ray sky map and to discover about 1000 new hard X-ray sources including possible new types of objects.
* Active galactic nuclei (AGN). The energy source of AGNs remains a mystery. It is probably from the interaction of massive black holes with the surrounding materials. HXMT will systematically study the hard X-ray emission properties and mechanism of various types of AGNs, especially the type II AGNs that are thought to be extremely absorbed.
* X-ray binaries. An X-ray binary involves a compact object (a black hole or a neutron star) and a normal star. HXMT will observe the hard X-ray spectra and temporal variability of X-ray binaries, study the formation and evolution of accretion disks, jets and black holes, and further test various general relativistic effects.
* Supernova remnants (SNRs). SNRs are longly thought to be the producer of cosmic-rays up to the 1015 eV. HXMT will study the nonthermal X-ray emission properties of SNRs and explore the particle acceleration at the shock front.
* Soft Gamma-ray burst Repeater (SGR). SGR are thought to be high energy transient sources associated with young highly magnetized neutron stars. The bursts are probably corresponding to the sudden magnetic energy release caused by the cracking of the neutron star crusts. HXMT can study the structure of magnetars, the matter state equation in strong magnetic field and with high density.
* Clusters of galaxies. Clusters of galaxies are the largest systems that are bounded gravitationally in the universe. HXMT will study the hard X-ray emission of clusters of galaxies and explore their origin.
* Gamma-ray bursts (GRBs). GRBs are the most violent explosions is the universe, and explaining their origin is a serious challenge to astrophysics. GRBs can be also used to explore the early universe."

China's first petaflop supercomputer to be fully assembled in late August - People's Daily Online
"China's first petaflop supercomputer to be fully assembled in late August
17:14, August 06, 2010
The main components of the "Tianhe-1," China's first domestically-made petaflop supercomputer, have been transported to Binhai District in Tianjin, and the computer is expected to be fully assembled in late August, according to the National Supercomputing Center in Tianjin on Aug. 5.
Three subsystems for computing, accessing the Internet, and input/output have reached Tianjin and are currently being installed. In addition, the supporting systems of cooling and power supply are ready for use. The "Tianhe-1" will be completely debugged after it is fully assembled, and if everything goes smoothly, it will be put into operation within 2010.
The "Tianhe-1" was successfully developed by the Changsha-based National University of Defense Technology in 2009, and China thus became the world's second country capable of developing petaflop supercomputers, only after the United States.
The "Tianhe-1" was ranked fifth on the list of the Top-500 supercomputers issued in November 2009. Onesecond calculations conducted by "Tianhe-1" are equivalent to 88 consecutive years of calculations by 1.3 billion people, and the data that the supercomputer can store is equivalent to the sum of the collections in four national libraries, each holding 27 million books.
The "Tianhe-1" will mainly be used for animation rendering, biomedical research, aerospace equipment development, processing of resource exploration and satellite remote sensing data, data analysis for financial engineering, weather forecasts, new materials development and design and theoretical calculations in general science."
"China's fastest supercomputer to have China-made chips
10:01, March 09, 2010
China's fastest supercomputer "Tianhe-1," ("Tianhe" meaning Milky Way), is to be equipped this year with China-made central processing unit (CPU) chips, replacing the only part of the computer that is currently imported.
Zhang Yulin, president of the National University of Defense Technology (NUDT) which developed the computer, told Xinhua Monday that the chips, also developed by the NUDT, are customized for this supercomputer.
"The new CPUs will greatly raise the peak speed and computing efficiency of 'Tianhe-1'," Zhang said on the sidelines of the annual session of the National People's Congress, the country's top legislature now meeting in Beijing.
"Tianhe-1," unveiled in October last year, could rival the world's most powerful computers. Theoretically, it is capable of more than one quadrillion calculations per second when operating at peak speed.
Experts note that one day's task for "Tianhe-1" might take 160 years for a mainstream dual-core personal computer to complete."

10:00, June 22, 2010
The 1,000 Genomes Project, which aims to produce an extensive catalog of human genetic variations, started to release data from a pilot phase Monday.
The project, a collaboration started in 2008 among research groups in the U.S., the United Kingdom, China and Germany, would support medical research and throw new light on human evolution, said Wang Jun, project coordinator of the Chinese party and also deputy head of the Shenzhen Branch of the Beijing Genomics Institute (BGI).
More than 50 trigabites of 8,000 billion base pairs of human DNA had been mapped and included in a public database, he said.
Researchers could gain free access to the data through three websites, including the 1,000 Genomes website (www.1000genomes.org), Wang said.
When completed, the database would contain human genetic information from the genomes of 2,500 people from 27 populations around the world.
BGI is responsible for mapping the genomes of 400 people of Mongoloid races and participants from the African populations.
Wang said the pilot project phase comprised three parts:
-- detailed comprehensive mapping of the genomes of six people from two core families;
-- less detailed comprehensive mapping of the genomes of 179 people;
-- mapping of the 1,000 genome exon (a DNA sequence that codes information for protein synthesis) of 700 people.
The results helped to evaluate the efficiency and effect of different mapping strategies. They will also help researchers to look closer at the genomes associated with human diseases.

(AsiaSatLink, April 2010)
Twenty years ago on 7 April 1990 at 9:30 p.m. Beijing time, AsiaSat 1, AsiaSats first regional satellite for Asia, was successfully launched from Xichang, China aboard a Long March 3 launch vehicle. This historic success not only marked the coming of age of satellite communications in Asia, but also the beginning of Chinas commercial launch service to the international market.
To commemorate this historic moment, China Great Wall Industry Corporation (CGWIC), the launch service provider of the Long March rocket, hosted a celebration dinner on the evening of 7 April and the Long March Users Conference on the following day, inviting guests from the worlds leading satellite operators, manufacturers and aerospace insurers and brokers to Xichang to celebrate this very special occasion and to further explore future cooperation opportunities with the China aerospace industry.
AsiaSat's Chief Executive Officer Peter Jackson was invited to deliver a speech at the celebration dinner. In his address, Mr. Jackson expressed great appreciation for CGWICs excellent service and tremendous support in the launch of AsiaSat 1. The successful launch of AsiaSat 1, Asias first private regional satellite, by the Long March rocket placed AsiaSat in the forefront of Asian satellite television and created a new era for the Asian satellite communications history.
Other AsiaSat representatives attending the event included Dr. Ya Hui Chiu, General Manager, Operations, who was also AsiaSats principal technical representative for the AsiaSat 1 launch; Zhang Hai Ming, General Manager, China; and Tik Yau, Manager, Satellite Control Centre."

Jiaolong China's Jiaolong sub, shown here under construction, will search
for energy sources and rare-earth metals in the deep sea. China Daily
Based at a new multi-million-dollar energy research station, a Chinese deep-sea sub will search for new energy sources and rare-earth metals on the ocean floor, according to Chinese state-run media.
Chinese officials announced Thursday that the new Jiaolong sub made 17 dives in the South China Sea this summer, the deepest to 12,332 feet (3,759 meters). The feat makes China the fifth country to dive past the 3,500 meter mark.
The 27-foot-long, 22-ton sub's main mission will be energy research, according to the state-run China Daily newspaper. It was designed to reach a depth of 23,000 feet (7,000 meters) and operate in most of the world's oceans, the newspaper says. No other submarine in the world is rated for that deep a dive.This spring, carrying a three-person crew, Jiaolong landed on the seafloor and planted a Chinese flag, along with a sign depicting the legendary dragon's palace. Jiaolong is the name of a mythical sea dragon.
Meanwhile, AFP is reporting that China plans to build a research base in the coastal city of Qingdao, in Shandong province, to serve as a support station for Jiaolong.
Engineers are starting design work on the 65-acre site, which would cost about $73 million, AFP says.
Scientists believe deep-sea beds at 13,200-19,800 feet (4,000-6,000 meters) hold abundant deposits of rare metals and methane hydrate, a solidified form of natural gas bound in ice, which could help satiate China's energy appetite.
China's energy exploration program began in 2002 with the design of Jiaolong, whose construction took six years. More than 100 Chinese companies were involved in the project, China Daily says.
China plants flag on seabed
HT Correspondent, Hindustan Times
Beijing, August 28, 2010
The robotic arm of a manned vehicle named after a mythical sea dragon has planted the Chinese flag in a secret location on the energy-rich and strategic South China seabed. China is now the fifth nation to successfully test this deep-sea diving technology. Chinas submersible, a 22-tonne and eight-metre-long submarine-like craft supported by a bigger vessel, is designed to scour the seabed 7,000 metres deep --- outpacing the technology of the US, France, Russia and Japan. Japans submersible is designed to dive 6,500 metres below sea. The Jiaolong has hit a depth of 3,759 metres in 17 dives from May to July this summer, eight years after technologists from 100 institutions and companies began the programme. Beijings science and technology ministry and the state oceanic administration announced the breakthrough only this week.
The state media said the technology is designed to search for new energy resources and rare earth. China is designing a nearly 73 million-dollar oceanic research base and support station for the submersible in the eastern port of Qingdao.
As the worlds first manned vehicle designed to reach 7,000 meters below sea level, the submersible can be used in 99.8 per cent of the worlds sea areas, chief designer Xu Qinan told the Chinese media. It represents the most advanced technology in deep-sea exploration. Each part of the submersible passed the pressure test of 7,000 meters, and in future we'll carry out 5,000-meter and 7,000-meter tests.
The Jiaolong holds a crew of three , if two crouch and one sits. The air pressure in the cabin is the same as on the surface. I felt excited and nervous every time I went deep underwater, crewmember Ye Cong told the media. Ye added that the vehicle is easy to maneuver. The vehicle operated underwater for nine hours and three minutes and beamed videos and photographs of the seabed.

Technology Review: A Simple Filter Could Make LCDs More Efficient
"A Simple Filter Could Make LCDs More Efficient
The new approach wastes far less light, saving energy.
By Katherine Bourzac
Technology. Published by MIT Review.
Monday, August 30, 2010
A new type of color filter could significantly increase the energy efficiency of liquid-crystal displays (LCDs), which dominate the market in everything from televisions to cell phones.
Color filter: The grating shown in the top image filters different colors of light depending on the width of its slits, and the distance between them. The bottom image shows the colors produced by the filter when its illuminated with white light.
Credit: Nature Communications
The best LCDs today only emit about 8 percent of the light produced by their backlights. This means that they drain batteries in portable electronics and ramp up electricity bills in homes (the California Energy Commission estimates that televisions consume 10 percent of the electricity in homes).
Normally, LCDs use several layers of optical devices to colorize, polarize, and shutter light from a backlight, and inefficiencies emerge at every step. Now researchers at the University of Michigan have made an optical film that promises to boost the overall efficiency of LCDs by more than 400 percent--so that 36 percent of light makes it through. The new optical film was developed by researchers led by L. Jay Guo, professor of electrical engineering and computer sciences at the university. The film colors and polarizes the light that passes through an LCD more efficiently than conventional components can.
The color filter is a three-layer sandwich of an insulating material in between two layers of aluminum; the entire stack is less than 200 nanometers thick and is etched with periodic slits, like a grate. The distance between the slits and their width determines the color they'll produce when illuminated by a white backlight. This is because the grating patterns are on the same size scale as the wavelength of visible light. In a paper published online last week in the journal Nature Communications, the Michigan researchers show that they can make a rainbow of colors using such a filter.
As well as being more efficient, the filter is also simpler to make than current LCDs, says Guo. It is possible to create red, blue, and green subpixels by patterning gratings of differing widths side by side in a single manufacturing step. Conventional LCDs use pigments to define the red, green, and blue subpixels that filter light from the backlight. Each of these colorants is deposited one at a time and then patterned to make a subpixel. The new gratings transmit more light than colorant-based filters; whereas a traditional green filter transmits about 40 percent of the light; a green, grating-based filter transmits 60 percent. Other colors have similar efficiency advantages.
The gratings also polarize the light very efficiently. This is vital, because the liquid-crystal shutters that open and close to let light from each pixel through only work with polarized light. Conventional displays use polarizing filters that absorb half the light--the portion with the wrong polarization. Guo's gratings let light of the right polarization pass though, but they don't absorb the other 50 percent--instead, this light is reflected back in the other direction. A mirror reflects this light and flips some of its polarization, allowing more light to pass back through the gratings.
Other researchers have made similar grating structures for focusing light or getting more light out of displays or solar cells. "It's a very easy structure to build and pattern," says Peter Catrysse, a researcher at Stanford University. He adds that Guo's color filter and polarizer shows versatility and tunability, a sign that the field is "getting closer to building components that can be used for practical purposes."
Nicholas Fang, a professor of mechanical science and engineering at the University of Illinois at Urbana-Champaign, sees other directions for the work. He notes that Qualcomm is working on even lower-power reflective displays. Combining this type of display with the new filter could eliminate the backlight altogether. "There's a possibility of building this [grating] as a reflective-based color filter," he says.
The Michigan researchers are now focused on making the filters "production worthy," or compatible with the machinery used to mass-produce displays, says Guo. Last year, his group demonstrated a way to use the same nanopatterning techniques over large areas at high speed on roll-to-roll printers. "We have used continuous roll-to-roll manufacturing to make very similar structures," he says. "The individual elements are there, and now it's a matter of integration."

Mr. Guo is Chinese. A Chinese made the discovery for the latest advance. Hence, it is appropriate to highlight the achievement of an ethnic Chinese (and probably still a Chinese citizen; it is unclear whether Mr. Guo has become a naturalized citizen). Also, at most, Mr. Guo is a Chinese-American. It is still appropriate to discuss the accomplishments of fellow Hans.
As a Chinese-American of Taiwan origin, I can assure you that in all of my years in meeting fellow Chinese-Americans and new Chinese immigrants, I have never met a Chinese or Chinese-American that insisted on only an American identity. It has never happened. Therefore, I am including Mr. Guo in this thread on accomplishments by Chinese.

Same Hans. Different cities.
I see the same increasingly-cosmopolitan Hans in merely different cities. I have lived in Taipei. Okay, I was only six. I have visited Beijing (e.g. Friendship hotel), Chongqing (e.g. guest of government research institute), Hong Kong (e.g. Century hotel?; memory getting fuzzy), and Singapore (e.g. near Raffles hotel). I felt very comfortable in each city.
Someday, I will visit Shanghai. I have been to the Sears Tower; renamed Willis Tower. I must see the Shanghai Tower after it's built.

So the Pyragon has definitely been my favourite Nerf blaster of the year and I've loved the way it looks with the black painted stock and Pinpoint sight, but sometimes you just get greedy and want..more. The whole "it'd be really cool if there was a tactical rail on the SIDE.."
I'm sure I'm not the only person in the world to have thought this, and this is where our friends at Sly Dev come in. In case you haven't heard of them, Sly Dev is a nifty lil' Australian company that sells very reasonably priced attachment pieces made from a 3D printer that you can glue onto your blaster, allowing you to add more attachments. They come in a variety of colours and are really well made and designed. Check out some of the pics after the jump or visit their site.
Iron sights, clip attachments, extra tactical rails, even a Jolt connector! We were very impressed with such a great idea:)

ALL DAY ZAZEN APRIL 28th
I just made a correction to the webpage. This month's all-day Zazen will not be on April 14th as previously announced, but on April 28th. This is because my wife Yuka is being introduced to American culture in the form of our inability to keep our hands off other peoples' property. Her wallet was stolen recently from her work place. And, trust me, ain't nobody even setting foot in the LUSH shop in Beverly Hills that needs to be stealing anybody's wallet. Her bike was stolen from in front of the shop a few months before that. Face it, Americans, we are scum sucking bastards. I'm at a total loss to explain our complete lack of moral standards in this country. There really is no excuse.
Anyhow, her green card was in the wallet & now she has to go to immigration and beg them to let her stay and help rebuild our economy (her shop is doing scads better ever since she took over as manager). Her appointment's on the 14th and since no one comes to these retreats for any other reason than to eat the food she makes, we've had to switch the date.

ROA Position on Plan to Overhaul Military Retirement
9 comments:
Frankly based the hostile tone of the question ROA should have ignored the question completely. When you are basically on duty 24/7 once you raise your hand we deserve a reasonable retirement and the current system is fair. I recommend screening out hostile questions next time.
- June 8, 2011 at 12:47 PM
Agree with Anonymous, June 8, 2011 @12:47 PM. Additionally, the answer is not to take away from those receiving reasonable compensation for their work and risk, but to acknowledge the increased risk Reservists currently face. Reservists who put it on the line in the "foxholes" deserve a proportional fair share of these "ridiculous" benefits. The country should not expect to reap peacetime benefits during a time of war. Reservists are absorbing the brunt of continuing the peace time levels of manning.
- June 8, 2011 at 1:24 PM
Anonymous 1247--Reservists are also on call 24/7 they just aren't paid 24/7. The phone rings at anytime here as well as at Active Duty homes, and in reality. Resevists are usually first out the door due to the nature of prior commitments handled day-to-day by our AD counterparts.

Then we should consider a single retirement system for all components based upon the RC age 60 retirement and 2008 NDAA adjustment. Instead of two separate inequitable retirement plans, everyone receives a 90 day reduction in retirement age (from age 60 to no less than age 50) for every 90 day period of active duty. This eliminates age 38 retirees and provides some equity in credit for time served. This may mean serving longer (AC or RC) to collect or leaving and getting another job until the age requirement is met. But it minimizes costs associated with double dipping retirees returning to perform their former military duties as a contractor or civil servant.
- June 8, 2011 at 4:02 PM
Of all the issues that really need attention in Washington, taking care of our military forces should be the priority!! After 31 years as a Reservist and served also active duty time, I am truly amazed how others appear to want to take control of what is left of our future. We have all given so much...yet Reserve have to also pay such high insurance premiums for TriCare if they haven't reached age 60. Why can't things be fair across the board? We have made a committment to serve our country, please assist us in our retirement years.
- June 9, 2011 at 8:11 AM
- Leonard Sobieski said...
The ROA position explains why changing the active duty retirement is not 100% perfect but doesn't really explain why it isn't the best option available. Sure, there will be differences in benefits for different year groups; however, how else could you ever fix this issue? As noted, there is no way you could politically get away with changing the retirement plan for those already serving but that isn't a good reason not to change compensation that is overly generous and based on circumstances that are no longer relevant (e.g., life expectancy of soldiers in trenches). The active duty retirement isn't reasonable compensation, it is over compensation and it hurts national security. ROA members need to realize that this isn't a union where we should fight for more benefits even though recruiting and retention is off the charts. Employee compensation packages have to come out of a budget that also pays for the equipment, etc. that everyone so desparately wants.

As an Air Reserve Technician who held dual status, DOD Federal Employee and an Air Force Reservist I was forced out of both of my jobs due to High Year of Tenure. I was able to collect my civilian retirement, however I have to wait until age 60 to collect my Reserve retirement. This was not the rule when I joined in 1971. I also missed out on the new GI bill transfer elgibility for my college age children.Not too many employers out there looking to hire a 55 year old person. If they are going to require you to leave both of your jobs you should be allowed to collect your Reserve retirement at the time your forced out.I was also activated for two and a half years but the early retirement bill was not retroactive back to 9/11, screwed again!
- June 11, 2011 at 10:21 AM
As unpopular as this may come across I believe that the military retirement reform will take place. The details about implementation yet to be determined. This may be the window to finally make Guard/Reserve retirements more equitable with their active duty members by allowing them 3 months for each 90 days of title 10 active duty supporting a contingency since 911. Capping this at age 57 which is the proposed earliest retirement age for active duty members.
