Description
With the task of supporting the development of FCC SRF cavities, a new cryogenic facility is under development at CERN. The facility shall provide the possibility to test single cavities in full reflection mode fitted with FPC coupler, HOM couplers and operated at cryogenic temperatures for the actual baseline of the FCC accelerator: its development is focused on 400 MHz cavities, operated at 4.5 K, and 800 MHz cavities, operated at 2 K. Flexibility is required to accommodate in the same facility different cavities sizes and different coupler positions.
With respect to similar facilities in other laboratories, the Horizontal Test Cryomodule (HTC) will take advantage of existing CERN infrastructures: its location has been identified with the M9 bunker of the SM18 test facility, already fitted with a valve box used for testing existing LHC and Isolde cryomodules.
Simplified process diagrams, definition of design pressure and temperatures as well as the preliminary heat load evaluation are presented. Provisional sizing of cryogenic lines has been as well completed.
A general overview of the cryomodule is then presented, with mention to the assembly procedures and to most relevant technical solutions implemented.
