Characteristics of a TV-rate electron bombardment CCD camera

We have developed the two kinds of Electron Bombardment CCD Camera employing a full frame transfer type and a frame transfer type electron bombardment sensor made by Hamamatsu Photonics. Especially in order to make a camera practicable for various application, we improve the image resolution and tried to measure the life of frame transfer type sensor. With regard to the resolution, there are many factors which degrades the resolution. This time, we reduced the gap length between a photo-cathode and a CCD to 60 percent of original one, hence, the sensor had greater resolution than 450 TV. Furthermore life of sensor is getting longer, because of the MPP CCD structure. C7162-20 Frame transfer Electron Bombardment CCD camera performs as a standard TV rate camera. From the point of camera performance, it can be replaced the SIT tube camera and I-CCD camera. In order to prove this fact, camera was compared with GEN 4 I-CCD camera which uses a small aperture MCP and a Blue-GaAs photo- cathode coupled to the CCD through optical fiber, and we show the result of comparison.
