An SRF Test Stand in High Intensity and High Energy Proton Beams
/ Vandoni, Giovanna (CERN) ; Artoos, Kurt (CERN) ; Baglin, Vincent (CERN) ; Brodzinski, Krzysztof (CERN) ; Calaga, Rama (CERN) ; Capatina, Ofelia (CERN) ; Claudet, Serge (CERN) ; Delprat, Laurent (CERN) ; Mehanneche, Scharif (CERN) ; Montesinos, Eric (CERN) et al.
In the framework of HL-LHC, a new infrastructure was installed in 2018, to test SRF structures in the proton beams of the SPS. Scope of the test stand is to study the operational performance of crab cavities for HL-LHC – more generally, SRF cavities – through a wide range of proton beam parameters up to high energy and current, under safe conditions for equipment and personnel.

Status of the HL-LHC Crab Cavity Tuner

The resonance frequency of the HL-LHC Double Quarter Wave (DQW) and Radio Frequency Dipole (RFD) crab cavities is set to the operating frequency of 400.79 MHz by deforming the cavities. For both types of cavities, the tuning principle foresees a symmetric mechanical deformation of parts of the cavities in vertical direction, with the tuner motor placed outside on top of the vacuum vessel.

RF Crab Cavities are an essential element of the High Luminosity LHC (HL-LHC) upgrade at CERN. Two RF dipole crab cavity used for the compensation of the horizontal crossing angle were recently manufactured and integrated into Titanium Helium tank and RF ancillaries necessary for the beam operation.
