HL-LHC prototype cryomodule completed

The HL-LHC project to increase the luminosity of the LHC met a key milestone this week when the first prototype crab cavity cryomodule for SPS was completed. The cavities included HOM couplers, thermal shields, supports and magnetic shield designed with Cockcroft engineers, and a cold magnetic shield manufactured by the Cockcroft Institute. Cockcroft Engineers were also involved in the measurements of the cavity all the way from trim tuning to high gradient testing of the dressed cavities.

The cryomodule will now undergo conditioning and cold testing in the SM18 test facility at CERN before being installed for testing with protons in the SPS at CERN. This is the first measurement of crab cavities with hadrons in the world and will mark a significant milestone in the project.
