Abstract

In this paper, we report on extremely good performance of 113 MHz SRF CW gun. This gun is a part of the system built to test coherent electron cooling concept and was aimed to generate trains of 78 kHz pulses with large 1 nC to 5 nC charge per bunch. While it was not built for attaining record low emittances, the machine can achieve very low normalized emittances ∼ 0.3 mm mrad with 0.5 nC charge per bunch using CsK2Sb photocathode. In addition to ex-cellent performance, this gun provides for very long lifetime of these high QE photocathodes, with a typical using time of 2 months.
