Tech.) ; Calaga, Rama (CERN) ; De Silva, Subashini (Jefferson Lab ; Old Dominion U.

For the 14 mrad crossing angle proposed, crab cavity systems are fundamentally anticipated for the viable operation of the International Linear Collider (ILC), in order to maximise its luminosity performance. Since 2021, a specialist development team have been defining optimum crab cavity technologies which can fulfil the operational requirements for ILC, both for its baseline centre-of-mass energy of 250 GeV, but also extending those requirements out to higher beam collision intensities.

Study of Cavity Imperfection Impact on RF-Parameters and Multipole Components in a Superconducting RF-Dipole Cavity
/ Olave, R G (Old Dominion U.) ; Delayen, Jean Roger (Old Dominion U.) ; De Silva, S U (Old Dominion U.) ; Li, Z (SLAC)
The ODU/SLAC superconducting rf-dipole cavity is under consideration for the crab-crossing system in the upcoming LHC luminosity upgrade. While the proposed cavity complies well within the rf-parameters and multipolar component restrictions for the LHC system, cavity imperfections arising from cavity fabrication, welding and frequency tuning may have a significant effect in these parameters.

Design and Prototyping of a 400 MHz RF-dipole Crabbing Cavity for the LHC High-Luminosity Upgrade
/ De Silva, S U (Old Dominion U.) ; Park, H (Old Dominion U.) ; Delayen, J R (Old Dominion U.) ; Li, Z (SLAC) ; Nicol, T H (Fermilab)
LHC High Luminosity Upgrade is in need of two crabbing systems that deflects the beam in both horizontal and vertical planes. The 400 MHz rf-dipole crabbing cavity system is capable of crabbing the proton beam in both planes. [...]

Trim Tuning of SPS-Series DQW Crab Cavity Prototypes
/ Verdú-Andrés, Silvia (Brookhaven Natl. Lab.) ; Baurac, Samuel (Adv. Design Consult., Lansing) ; Boulware, Charles (Adv. Design Consult., Lansing) ; Clemens, William (Jefferson Lab) ; Grimm, Terry (Adv. Design Consult., Lansing) ; McEwen, Anne (Jefferson Lab) ; Park, HyeKyoung (Old Dominion U. ; Jefferson Lab) ; Ratti, Alessandro (LBNL, Berkeley ; SLAC) ; Skaritka, John (Brookhaven Natl. Lab.) ; Wu, Qiong (Brookhaven Natl. Lab.) et al.
The final steps in the manufacturing of a superconducting RF cavity involve careful tuning before the final welds to match the target frequency as fabrication tolerances may introduce some frequency deviations. The target frequency is chosen based on analysis of the shifts induced by remaining processing steps including acid etching and cool down. [...]
