Status of the HL-LHC Crab Cavity Tuner
/ Artoos, Kurt (CERN) ; Arnaudon, Luca (CERN) ; Calaga, Rama (CERN) ; Cano-Pleite, Eduardo (CERN) ; Capatina, Ofelia (CERN) ; Capelli, Teddy (CERN) ; Cartaxo dos Santos, Duarte (CERN) ; Garlasché, Marco (CERN) ; Glenat, David (CERN) ; Krawczyk, Artur (Cracow, INP ; CERN) et al.
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.
