Description
A new QWR SRF electron gun has been designed as a low-emissivity light injector for LCLS-II-HE, and a prototype is currently being developed in collaboration between SLAC, FRIB, HZDR, and ANL. The new gun will use an HZDR-type cathode, which includes a cathode load-lock (cathode stalk) developed by FRIB and a complex cathode exchange system designed by HZDR. A dedicated alignment process allows the cathode to be precisely aligned to the axis of cathode stalk without touching the cathode plug itself, ensuring particle-free exchange. At the same time, a chamber system has been built to transfer one cathode from the clean room to the electron gun under a request clean environment.
