论文摘要
CERN加速器复合物为大型强子对撞机（LHC）的相互作用区域的四个大实验制备质子，以及许多固定的靶实验，这些实验直接从LHC注射器中吸收光束。在2010年至2021年之间，在LHC注射器升级（LIU）项目下设计并实施了一系列重大变化，其主要目标是使喷油器链能够生产具有强度和亮度翻倍的LHC梁。作为这些升级的副产品，固定目标梁也有望受益，并且可能访问参数范围先前未探索。这封信总结了LHC注射器产生的主要固定目标光束，它们的预期性能是在各种梁类型的升级后进行的，并显示了2021梁调试的首先结果。
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.
