A step closer to the CW high brilliant beam with SRF gun II

In order to achieve CW electron beam with a high average current up to 1 mA and a very low emittance of 1 um, an improved superconducting photoinjector (SRF Gun II) has been installed and commissioned at HZDR since 2014. This new gun replaces the first 3.5-cell SRF gun at the SC Linac ELBE. 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 beam line. The results agree with the simulation very well. The photocathode transfer system has been installed for the first high current beam test planned in 2015. In this contribution the results of the commissioning and the first beam parameters will be presented in detail.
