Description
A novel travelling-wave RF photogun driven by ultra-short RF pulses has been successfully tested, stably reaching cathode fields over 160 MV/m. This performance surpasses current S-band photoguns and represents a significant step toward increasing the brightness of SwissFEL. Installed at the C-band test stand at PSI, the system demonstrates stable and robust high-power operation. We present an overview of the RF design, its unique tuning-free implementation, and high-power performance, highlighting how travelling-wave gun technology opens new opportunities for advanced electron sources.
