Collimation activities for FCC-hh


Introduction

With the goal of colliding proton beams at an energy of 50 TeV, the total stored energy per beam at the FCC-hh will be of about 8 GJ, more than one order of magnitude larger than at the LHC. The handling of high intensity beams and the associated high loss rates of protons require a powerful collimation system to prevent quenches of superconducting magnets in regular operations and material damage in case of irregular beam losses. The present studies aim at defining a first conceptual solution for a collimation system fullfilling the global requirements of the FCC-hh.
