LHC喷油器链升级后的性能和潜在开发

Performance of the LHC injector chain after the upgrade and potential development

Hannes Bartosik, Giovanni Rumolo

摘要:

欧洲核子研究中心的加速器复合体为大型强子对撞机(LHC)相互作用区的四个大型实验以及一些固定目标实验准备质子,这些实验直接从LHC注入器获得光束。在2010年至2021年期间,LHC注入器升级(LIU)项目下的注入器综合体设计和实施了一系列重大变化,主要目标是使注入器链能够产生强度和亮度加倍的LHC光束。作为这些升级的副产品,固定目标波束也有望受益,并可能访问以前未探索的参数范围。这封信总结了LHC注入器产生的主要固定目标光束,以及各种光束类型升级后的预期性能,并显示了2021年光束调试的初步结果。

英文摘要:

The CERN accelerator complex prepares protons for the four big experiments at the Interaction Regions of the Large Hadron Collider (LHC) as well as for a number of fixed target experiments, which take beam directly from the LHC injectors. Between 2010 and 2021, a series of major changes were designed and implemented to the injector complex under the LHC Injectors Upgrade (LIU) project, with the main goal to enable the injector chain to produce LHC beams with doubled intensity and brightness. As a byproduct of these upgrades, the fixed target beams are also expected to benefit and possibly access parameter ranges previously unexplored. This letter summarises the main fixed target beams produced by the LHC injectors, their expected performance after the upgrade for the various beam types and shows first results from 2021 beam commissioning.
