A High Average Power RF Photo Injector Gun Cavity

Frank Marhauser
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.
