The unique feature of the gun is that a photocathode is held at room temperature. It allowed to preserve the quantum efficiency of Cs2KSb cathode which is adversely affected by cryogenic temperatures. Relatively low frequency permitted fully realize the accelerating field gradient what in in turn helps to achieve 10 nC charge and 0.3 microns normalized emittance. We present the achieved performance an operational experience as well. PB - JACoW Publishing CP - Geneva, Switzerland ER -
