A High Average Power RF Photo Injector Gun Cavity
BESSY, Berlin Germany
Based on the 1.3 GHz normal conducting RF photo gun installed at the
Free Electron Laser in Hamburg (FLASH) a new RF gun prototype with an optimized cooling layout has been developed at
BESSY with the objective to operate in the 100 kW average power regime. This would significantly enhance the capability
of present L-Band guns towards operation at higher accelerating fields or/and duty factors. High power RF-conditioning
at the Photo Injector Test Facility at DESY in Zeuthen (PITZ) has recently been performed achieving 47 kW average power
and an electric peak field of 53 MV/m in maximum respectively, so far only limited by power constraints of the RF-system.
RF-conditioning and simulation results are presented.
