CERN目前正在对整个LHC注入器链进行雄心勃勃的改进计划，以便能够提供具有挑战性的HL-LHC参数的光束。LHC注入器升级项目协调了这一大规模的升级计划，并涵盖了一个新的直线加速器（Linac 4项目）以及质子同步加速器助推器，质子同步加速器和超级质子同步加速器的升级。重离子注入器链也包括在内，将Linac 3和低能离子环添加到有关加速器的列表中。将介绍主要升级的性能目标和路线图，包括工作状态和前景。将讨论LHC运行2期间的机器研究和里程碑，并给出初步的长周期2安装计划。最后，对于LHC运行3，将估计所有升级后整个注入器链的束流性能，并概述所需的调试阶段。
CERN is currently carrying out an ambitious improvement programme of the full LHC Injectors chain in order to enable the delivery of beams with the challenging HL-LHC parameters. The LHC Injectors Upgrade project coordinates this massive upgrade program, and covers a new linac (Linac4 project) as well as upgrades to the Proton Synchrotron Booster, the Proton Synchrotron and Super Proton Synchrotron. The heavy ion injector chain is also included, adding the Linac3 and Low Energy Ion Ring to the list of accelerators concerned. The performance objectives and roadmap of the main upgrades will be presented, including the work status and outlook. The machine studies and milestones during LHC Run 2 will be discussed and a preliminary Long Shutdown 2 installation planning given. Finally, for the LHC Run 3, the beam performance across the full injector chain after all the upgrades will be estimated and the required commissioning stages outlined.
