Design study of a beta=0.09 high current superconducting half wave   resonator
  There's presently a growing demand for high current proton and deuteron linear accelerators based on superconducting technology to better support various fields of science. A \b{eta}=0.09 162.5 MHz high current superconducting half wave resonator (HWR) has been designed at Peking University to accelerate 100 mA proton beam or 50 mA deuteron beam after the RFQ accelerating structure. The detailed electromagnetic design, multipacting simulation, mechanical analysis of the cavity will be given in this paper.
