Crab Cavity Prototype Development and Test Stand Installation in the SPS and World’s First Crabbing of a Proton Beam
The first test of superconducting crab cavities to rotate a beam of protons was performed on 23 May 2018 using a beam from CERN’s Super Proton Synchrotron (SPS) accelerator. These cavities are a key component of the High Luminosity Large Hadron Collider (HL-LHC). A total of 16 such cavities will be installed in the HL-LHC…

Highlights from the HL-LHC Work Packages
WP2: Performance and Beam Dynamics Following the project re-baselining in summer 2016, the layout and optics of the high luminosity insertion regions were reviewed and the performance re-evaluated. This has led to a small but visible reduction in performance, reducing the margins available for the achievement of the nominal and ultimate luminosity targets. Optimization of…
