Description

The in-situ photocathode research system integrates preparation, testing, and environmental control with real-time data linkage to prevent contamination during photocathode transfer. It enables real-time parameter optimization for high-performance photocathodes through material characterization, while also evaluating performance and defining operational conditions for electron gun applications. After comprehensive integration and debugging, the system successfully prepared Cs2Te photocathode with CsBr protective layer, enabled temperature-dependent studies, and conducted in-situ X-ray characterization at the Shanghai Synchrotron Radiation Facility. GIWAXS analysis reveals a direct correlation between quantum efficiency improvements and crystalline structural changes, validates the system's effectiveness in advancing next-generation photocathode research.
