大型强子对撞机 (LHC) 及其高光度 (HL) 升级预计将存储高达 700 MJ 的前所未有的光束能量。准直系统负责清洁光束晕，对于机器的成功运行至关重要。基于 Tevatron 设计和操作经验 [1]，大型强子对撞机正在考虑使用空心电子透镜 (HEL) 进行主动光晕控制。 HEL 可用作软刮刀装置，并且可以在梁芯附近运行而不会受到损坏 [2]。我们使用 Merlin C++ 加速器库 [3] 来实现 HEL，并检查各种测试场景对光束光晕的影响。
The Large Hadron Collider (LHC) and its High Luminosity (HL) upgrade foresee unprecedented stored beam energies of up to 700 MJ. The collimation system is responsible for cleaning the beam halo and is vital for successful machine operation. Hollow electron lenses (HELs) are being considered for the LHC, based on Tevatron designs and operational experience [1], for active halo control. HELs can be used as soft scraper devices, and may operate close to the beam core without undergoing damage [2]. We use the Merlin C++ accelerator libraries [3] to implement a HEL and examine the effect on the beam halo for various test scenarios.
