| Popis: | Many future particle colliders require beam crabbing to recover geometric luminosity loss from the nonzero crossing angle at the interaction point (IP). A first demonstration experiment of crabbing with hadron beams was successfully carried out with high energy protons. This breakthrough result is fundamental to achieve the physics goals of the high luminosity LHC (HL-LHC) and the future circular collider (FCC). The expected peak luminosity gain (related to collision rate) is 65% for HL-LHC and even greater for the FCC. Novel beam physics experiments with proton beams in CERN’s Super Proton Synchrotron (SPS) were performed to demonstrate several critical aspects for the operation of crab cavities in the future HL-LHC including transparency with a pair of cavities, a full characterization of the cavity impedance with high beam currents, controlled emittance growth from crab cavity induced rf noise. This research is supported by the HL-LHC project, US Department of Energy and UK Science and Technology Council through HL-LHC-UK. The authors thank the members of HL-LHC WP4 (crab cavity) Collaboration and CERN departments for their invaluable contributions. A special acknowledgement to the CARE, EuCARD, and US-LHC Accelerator Research Program (LARP) for their important role in enabling this research during the R&D phase. We also acknowledge the contributions of KEKB and Niowave Inc. to the crab cavity R&D. |
