Description
The first RF Dipole crab cavity cryomodule, jointly developed by CERN and UK-STFC under the HL-LHC project, was built for proton beam tests in the SPS machine. In 2024, the cryomodule was tested in the CERN horizontal test facility prior to its installation in the SPS. During acceptance tests, two critical non-conformities related to the fundamental power couplers were identified. This paper presents the mitigation of these non-conformities and the subsequent validation tests that led to successful continuous wave (CW) operation. Key aspects of RF performance, cryogenics, alignment, and frequency tuning are also discussed.
