CERN 的 AWAKE 项目计划研究质子驱动的等离子体尾场加速。来自 SPS 的质子束将用于驱动 10 m 长的铷等离子体电池中的尾场。该实验计划于2016年进行，第一阶段将详细研究等离子体中质子束的自调制，而第二阶段将向等离子体尾场注入外部电子束以探测加速过程。 AWAKE 在前 CNGS 实验区的安装和所需的光学灵活性定义了电子束线设计要满足的严格边界条件。 1.25·10 电子的低能量（10-20 MeV）束的传输和具有高强度质子束（3·10）的同步共传播决定了磁体和束诊断的一些技术和操作挑战。本文介绍了电子线布局和相关设备的现状。
The AWAKE project at CERN is planned to study proton driven plasma wakefield acceleration. The proton beam from the SPS will be used in order to drive wakefields in a 10 m long Rubidium plasma cell. In the first phase of this experiment, scheduled in 2016, the self-modulation of the proton beam in the plasma will be studied in detail, while in the second phase an external electron beam will be injected into the plasma wakefield to probe the acceleration process. The installation of AWAKE in the former CNGS experimental area and the required optics flexibility define the tight boundary conditions to be fulfilled by the electron beam line design. The transport of low energy (10-20 MeV) bunches of 1.25·10 electrons and the synchronous copropagation with much higher intensity proton bunches (3·10) determines several technological and operational challenges for the magnets and the beam diagnostics. The current status of the electron line layout and the associated equipment are presented in this paper.
