Status and running experience of the SRF gun at HZDR — •rong xiang, andre arnold, pengnan lu, petr murcek, jochen teichert, and hannes vennekate — Helmholtz Zentrum Dresden Rossendorf, 01328 Dresden

In order to achieve a high average current up to 1 mA with a low emittance of 1 mm mrad at 77 pC, an improved SRF gun has been installed and commissioned at HZDR since 2014. This new gun replaces the first 3.5-cell SRF gun at the superconducting linear accelerator ELBE which had been in operation since 2007. The new gun has been tested first with a Cu photocathode. The RF performance of the niobium cavity has been evaluated, the transverse and longitudinal beam parameters for low charge bunches have been measured, and the first beam has been guided into the ELBE beamline. The photocathode transfer system is also installed for the first high current beam test in 2015. In this contribution the status of the gun and the results of this first measurement period will be presented in detail.
