Spectral response measurements on photocathodes for bERLinPro — •Hans Kirschner, Martin Schmeißer, Julius Kühn, Thorsten Kamps, and Andreas Jankowiak — Helmholtz-Zentrum Berlin

Photocathodes of the alkali antimonide group are promising candidates for the generation of electron beams with high brightness and high average current for Energy Recovery Linacs such as bERLinpro. The spectral response (spectrally resolved quantum efficiency) is an important figure of merit and depends strongly on the surface composition and crystal phases present in the sample. We present an optical setup that will allow in-situ measurements of photocathode samples in our preparation system.
