Description
A novel travelling-wave (TW) RF photogun driven by ultra-short RF pulses has been successfully tested, stably reaching cathode fields of 170 MV/m for 100 ns pulses and 190 MV/m for a 10 ns pulse. This cathode surface electric field gradient far surpasses current S-band photoguns and represents a significant step toward increasing the brightness of future XFELs. Here we present an overview of the RF design, its unique tuning-free implementation, and highpower performance, highlighting how TW RF Photogun technology opens new opportunities for advanced electron
sources.
