High Luminosity LHC Optics and Layout HLLHCV1.4

Abstract

Abstract The goal of the High Luminosity Project is the upgrade of the LHC to deliver an integrated luminosity of at least 250 fb-1 per year in each of the two high-luminosity, general-purpose detectors ATLAS and CMS. This article presents the latest layout design and the corresponding optics features, which comprise optimisation of the orbit corrector and crab cavity systems, and new estimates of the performance reach thanks to the new concept of fully remote alignment. In addition, the new optics version incorporates improvements required by beam instrumentation, dump system, and collimation system, as well as low-beta solutions for the LHCb experiment.
