Simulating Novel Collimation Schemes for High-Luminosity LHC With Merlin++

Research output: Chapter in Book/Report/Conference proceedingConference contribution


Due to the large stored beam en­ergy in the HL-LHC new col­li­ma­tion tech­nolo­gies must be used to pro­tect the ma­chine. Ac­tive halo con­trol of the pro­ton beam halo with a Hol­low Elec­tron Lens can give a kick to pro­tons at the edge of the beam with­out ef­fect­ing the core. Var­i­ous modes of op­er­a­tion are pos­si­ble for ex­am­ple the elec­tron lens can have a con­tin­u­ous cur­rent or it can be pulsed to dif­fer­ent am­pli­tudes for each pas­sage of the pro­ton beam. In this ar­ti­cle we use Mer­lin++ sim­u­la­tions to show the per­for­mance of these modes for HL-LHC pa­ra­me­ters. We also pre­sent re­cent sim­u­la­tions com­par­ing scat­ter­ing mod­els in Mer­lin++.
