Abstract:
For the bERLinPro energy recovery LINAC, HZB is developing a superconducting 1.4-cell electron gun, which, in its final version, is planned to be capable of CW 1.3 GHz operation with 77 pC/bunch. For this purpose a series of three superconducting cavities, denoted as Gun 1.0, Gun 1.1 (both designed for 6 mA) and Gun 2.0 (100 mA) is foreseen. Gun 1.0 now reached rf commissioning status and the Gun 1.1 cavity is completely manufactured. In the paper the chronology of manufacturing, tuning and processing of the Gun 1.1 cavity is described, including details about combined mechanical/ electrodynamic simulations, which were performed in order to gain deeper understanding of the cavity's unexpected tuning behavior.
