Challenges for the mechanical design of the LHC collimation system

by Alessandro Bertarelli (CERN)

Europe/Zurich
Description

The collimation system of CERN Large Hadron Collimator (LHC) represents one of the most critical systems of the accelerator, given the unprecedented energies stored in its beams.

The design of the collimators must comply with a number of stringent requirements to ensure an adequate beam cleaning during normal operation and an effective machine protection in case of beam accidents; these requirements are becoming even more demanding for the High Luminosity upgrade of the LHC (HL-LHC), whose implementation is currently ongoing.

In this seminar the mechanical designs of LHC and HL-LHC collimators are presented, focusing in particular on the complex thermo-mechanical simulations required by the extreme phenomena which might be induced in case of accidents, on the selection of the materials that are to withstand such events and on the experimental tests required to validate materials and components exposed to interactions with energetic particle beams.
