STATUS AND FIRST RESULTS FROM THE UPGRADED PITZ FACILITY

Since December 2004, the photo injector test facility at DESY in Zeuthen (PITZ) has been upgraded. A normal conducting booster cavity has been installed and the diag-nostics beamline was significantly modified. An extended water cooling system has been installed and was success-fully taken into operation. Currently, the new diagnostics elements are being commissioned. Since the installation of the new 10 MW klystron in June/July, the gun is being conditioned towards higher peak and average power, and the whole beamline including the booster is being taken into operation. First results from the commissioning phase including gun and booster conditioning are reported
