Research paperExperimental GrowthExperimental CharacterizationOperation of Cs-Sb-O activated GaAs in a high voltage DC electron gun at high average currentJai Kwan Bae, Matthew Andorf, Adam Bartnik, Alice Galdi et al.arXiv preprint·2022·10.1063/5.0100794·arXiv:2205.13632AbstractNegative Electron Affinity (NEA) activated GaAs photocathodes are the most popular option for generating a high current spin-polarized electron beam, but their operational lifetime is limited by vacuum sensitivity. This work compares Cs-Sb-O and Cs-O activated GaAs photocathodes in a high-voltage DC electron gun at 200 keV and high average current, showing a spectral dependence of lifetime improvement and a 45% increase in charge lifetime at 780 nm for Cs-Sb-O relative to Cs-O.Read more
