先进的质子驱动等离子体韦克菲尔德加速实验（AWAKE）是欧洲核子研究中心的一个项目，旨在加速由质子束驱动的等离子体韦克菲尔德中的电子束。等离子体是在一个10米长的铷蒸气室使用脉冲钛：蓝宝石激光诱导，与韦克菲尔德形成的质子束从欧洲核子研究中心的超级质子同步加速器（SPS）。一个16 MeV的电子聚束同时注入到等离子体单元中，由韦克菲尔德加速到GeV范围内的能量在这个短距离内。在质子和激光束成功运行后，电子束线于2017年底安装并调试，以产生合适的电子束并将其注入等离子体电池。为了实现实验的目标，重要的是要有可靠的束流仪器测量质子，电子和激光束的各种参数。本文介绍了AWAKE中束流仪器的现状，并报告了2017年AWAKE运行期间取得的性能。
The Advanced Proton Driven Plasma Wakefield Acceleration Experiment (AWAKE) is a project at CERN aiming to accelerate an electron bunch in a plasma wakefield driven by a proton bunch. The plasma is induced in a 10 m long rubidium vapor cell using a pulsed Ti: Sapphire laser, with the wakefield formed by a proton bunch from the CERN Super Proton Synchrotron (SPS). A 16 MeV electron bunch is simultaneously injected into the plasma cell to be accelerated by the wakefield to energies in the GeV range over this short distance. After successful runs with the proton and laser beams, the electron beam line was installed and commissioned at the end of 2017 to produce and inject a suitable electron bunch into the plasma cell. To achieve the goals of the experiment, it is important to have reliable beam instrumentation measuring the various parameters of the proton, electron and laser beams. This contribution presents the status of the beam instrumentation in AWAKE and reports on the performance achieved during the AWAKE runs in 2017.
