Abstract:
Abstract As a first step towards a high brightness, high average current electron source for the BERLinPro ERL a fully superconducting photo-injector was developed by HZB in collaboration with Jefferson Laboratory, DESY and the A. Soltan Institute. This cavity-injector ensemble is made up of a 1.6-cell superconducting cavity with a superconduct- ing lead cathode deposited on the half-cell backwall. A superconducting solenoid is used for emittance compensa- tion. This system, including a diagnostics beamline, has been installed in the HoBiCaT facility to serve as a testbed for beam dynamics studies and to test the combination SRF cavity and superconducting solenoid. This paper summa- rizes the characterization of the cavity in this configuration including Q measurements, dark current tests and field- stability analyzes.
