The Rossendorf SRF gun has been successfully put into operation at the ELBE accelerator facility with average current up to 250 μA. In order to achieve higher current and better beam quality, new updates are going on. One of the recent activities is to develop a new GaAs(Cs,O) photocathode preparation and transportation system. In this presentation we will show the status of GaAs cathode preparation, and also the XHV transfer vessel which allows for the efficient cathode transport from the preparation chamber into the SRF gun or to the analysis devices.
