The collaborative development of an optimised cavity/cryomodule solution for application on ERL facilities is nearing completion. This paper outlines the progress of the module assembly and details the processes used for final cavity string integration. The preparation and installation of the high power couplers will be described, as will that of the HOM loads. The testing and integration of the various sub-components of the cryomodule are also detailed in this paper.

During the XFEL prototype module tests on the module test stand at DESY RF power measurement anomaly on the high order mode (HOM) couplers on the cavity operating frequency was detected and investigated. HOM coupler multipacting, predicted by the analythical simulations, was found to be the source of the anomalous signal peak. TESLA type SRF cavity HOM coupler multipacting simulations and observations are presented, compared and discussed.

In collaboration with Jefferson Laboratory, DESY and the A. Soltan Institute HZB developed a fully superconducting RF photo-injector as a first step towards a high average current electron source for the BERLinPro ERL. This setup consists of a 1.6 cell superconducting gun cavity with a lead cathode plasma-arc deposited on the half cell backwall and a superconducting solenoid. The system, including a warm diagnostic beam-line section, was recently installed in the HoBiCaT test facility to study beam dynamics within the ERL parameter range. This paper will give an overview of the horizontal cavity tests, dark current studies and beam measurements.
