Linac4是一个普通的160 MeV超导加速器，目前正在欧洲核子研究中心安装并逐步投入使用。它将取代老化的50 MeV Linac2作为PS助推器（PSB）的注入器，同时由于更高的注入能量，其亮度增加了两倍。这将是为满足高亮度大型强子对撞机项目的需要而增加大型强子对撞机注入器光束亮度的第一步。在专用测试台上进行一系列光束测量后，3 MeV Linac4前端，包括离子源、RFQ和光束斩波线，已经在Linac4隧道的最终位置重新投入使用。下面部分的试运行，漂移管直线加速器，正在开始。光束调试将逐步增加能量，到2015年达到最终的160 MeV。在Linac4连接到PSB之前，将在2016年进行扩展波束测量阶段，包括对PSB剥离设备的测试，以及为期一年的测试运行，以评估和提高Linac4的可靠性，这将在下一次LHC长时间关闭期间进行。
Linac4 is a normal conducting 160 MeV Hlinear accelerator presently being installed and progressively commissioned at CERN. It will replace the ageing 50 MeV Linac2 as injector of the PS Booster (PSB), increasing at the same time its brightness by a factor of two thanks to the higher injection energy. This will be the first step of a program to increase the beam brightness in the LHC injectors for the needs of the High-Luminosity LHC project. After a series of beam measurements on a dedicated test stand the 3 MeV Linac4 front-end, including ion source, RFQ and a beam chopping line, has been recommissioned at its final position in the Linac4 tunnel. Commissioning of the following section, the Drift Tube Linac, is starting. Beam commissioning will take place in steps of increasing energy, to reach the final 160 MeV in 2015. An extended beam measurement phase including testing of stripping equipment for the PSB and a year-long test run to assess and improve Linac4 reliability will take place in 2016, prior to the connection of Linac4 to the PSB that will take place during the next long LHC shut-down.
