The Cavity-String beamline and Fundamental Power Couplers were assembled in the ISO4 cleanroom jointly with STFC and CERN staff.

Two prototypes of RF dipole cavities which provide horizontal crabbing for the HL-LHC were successfully built at CERN. The frequency tuning setup before the final two welds is shown in the figure below.

In the framework of HL-LHC AUP in the US, last year two prototype RF Dipole Crab Cavities manufactured in Italy by Zanon Research & Innovation were validated successfully at FNAL through cold tests at 2K.

CERN, STFC Daresbury Laboratory (STFC-DL) and Lancaster University have collaboratively designed a pre-series cryomodule to house 2 “RF Dipole” type Crab Cavities, with the aim of assembling the module at Daresbury Laboratory and testing at CERN in 2023.
