CERN SRF ASSEMBLING AND TEST FACILITIES

CERN is currently upgrading and refurbishing its RF and cryogenic facilities in the SM18 assembly hall with the aim of testing SRF cavities and cryo-modules of various provenience. They concern new and spare cavities for the HIE-Isolde upgrade, SPL study and LHC collider. These projects require a redistribution of space, refurbishment of cleanrooms, modification of SRF test stands, of vertical cryostats and of all cryogenic lines. This article presents the specifications of the refurbished facility and the technical choices required for the assembling, processing and testing of superconducting RF cavities.
