An electron beam's quality is fundamentally limited by its attributes at the cathode. The emission from photocathodes can be bright, but not necessarily uniform. Quantum efficiency (QE) maps generated by selectively illuminating the cathode surface r

A key system component in many advanced RF sources and beam devices is a high brightness photoinjector producing a high quality electron beam. The principal component is the photocathode producing electron bunches using the photoelectric effect. This

A novel self-healing hybrid-diffuser cesium reservoir photocathode is demonstrated. The model-driven design optimizes operating temperature to match diffusion and evaporation rates and maximize quantum efficiency of the cesiated tungsten surface. A s

To meet future demands of free electron lasers, reliable and long lasting photocathodes are needed. With current photocathodes lacking a sufficient combination of both lifetime and high quantum efficiency, research continues to explore ways to formul
