Description

The photocathode in-situ research apparatus integrates preparation, characterization, and environmental control under ultra-high vacuum to prevent surface contamina-tion, establishing a real-time “preparation-monitoring-regulation” closed-loop for high-performance photocath-odes such as Cs2Te. Following comprehensive commis-sioning, which is utilized for Cs2Te photocathode prepara-tion, CsBr protective layer deposition, and temperature-dependent performance measurements. In-situ grazing-incidence wide-angle X‑ray scattering (GIWAXS) charac-terization at the Shanghai Synchrotron Radiation Facility (SSRF) revealed that the crystal structure of sequentially deposited Cs2Te photocathode changes synchronously with the QE improvement, validating the apparatus for studying high QE photocathodes.
