For the first time, a superconducting RF gun where a photo cathode is inside a superconducting cavity has been working stably over a periode of seven weeks. The gun with a half cell cavity has been operated in the cryostat at 4.2K. A maximal field strength of 22MV/m in the cavity and maximal beam energy of 900keV have been obtained. Measurements of beam current, transmission, energy spread and transverse emittance are presented.
