Abstract
The quality of the photocathodes is critical for the stability and reliability of the photoinjector’s operation. Thanks
to the robust magnesium and Cs2Te photocathodes, SRFgun-II at HZDR has been proven to be a successful example
in CW mode for high current user operation.
In this contribution, we will present our observation of the QE evolution of Cs2Te photocathodes during SRF gun
operation. The variables including substrate surface, film thickness, Cs/Te stoichiometric, multipacting, RF loading
and charge extract are considered in the analysis.
