A Cu Photocathode for the Superconducting RF Photoinjector of BERLinPro

, 2018
The initial commissioning of the Superconducting RF SRF photoinjector is achieved with a Cu photocathode due to its robustness with respect to interactions with the SRF cavity of the injector. Here we present the preparation and characterization of

Observation of a charge limit for photocathode electron guns [PDF]

, 1992
The Photocathode Electron Gun (PEG) at SLAC is required to produce bunch intensities of up to 10{sup 11} electrons within 2 ns (8 Amps). Operation of PEG has demonstrated a `Charge Limit` phenomenon, whereby the charge that can be extracted from the gun ...
