标题： Particle physics applications of the AWAKE acceleration scheme

摘要： AWAKE实验在运行1（2016-8）中取得了非常成功的成果，首次通过观察长质子束调制为微束以及在10米等离子体中将电子加速到2 GeV，展示了质子驱动的等离子体尾波加速。 AWAKE运行2（2021-4）的目标是将高电荷的电子束加速到高能量，约10 GeV，同时在等离子体中保持束流质量，并证明该过程具有可扩展性。 因此，AWAKE方案是一种在短距离内加速电子到高能量的有前景的方法，从而开发出可用于粒子物理实验的可用技术。 使用SPS的质子束，电子束的加速达到约50 GeV是可能的。 使用LHC质子束驱动尾波可能会产生多TeV的电子束，例如在4公里的等离子体中实现3 TeV的加速。 本文概述了AWAKE方案在粒子物理中的一些应用，并表明AWAKE技术可能带来其他方式无法实现的独特设施和实验。 特别是，提出了寻找暗光子、测量强场QED以及研究电子-质子碰撞中的新物理的实验。 社区也被邀请考虑用于TeV尺度电子束的应用。 显示英文摘要

摘要： The AWAKE experiment had a very successful Run 1 (2016-8), demonstrating proton-driven plasma wakefield acceleration for the first time, through the observation of the modulation of a long proton bunch into micro-bunches and the acceleration of electrons up to 2 GeV in 10 m of plasma. The aims of AWAKE Run 2 (2021-4) are to have high-charge bunches of electrons accelerated to high energy, about 10 GeV, maintaining beam quality through the plasma and showing that the process is scalable. The AWAKE scheme is therefore a promising method to accelerate electrons to high energy over short distances and so develop a useable technology for particle physics experiments. Using proton bunches from the SPS, the acceleration of electron bunches up to about 50 GeV should be possible. Using the LHC proton bunches to drive wakefields could lead to multi-TeV electron bunches, e.g. with 3 TeV acceleration achieved in 4 km of plasma. This document outlines some of the applications of the AWAKE scheme to particle physics and shows that the AWAKE technology could lead to unique facilities and experiments that would otherwise not be possible. In particular, experiments are proposed to search for dark photons, measure strong field QED and investigate new physics in electron-proton collisions. The community is also invited to consider applications for electron beams up to the TeV scale.
