在等离子体加速器的加速/聚焦尾流场中振荡的相对论性电子发射电磁辐射，称为电子辐射（BR）。质子驱动等离子体尾流场加速已在欧洲核子研究中心的高级尾流场实验（AWAKE）中得到证实；然而，与激光和电子束驱动的等离子体加速器相比，对其伴随辐射发射的研究较少。本文对AWAKE中的BR进行了详细的仿真研究。考虑到AWAKE Run 2（2021 -）的新设置，使用粒子池模拟研究了见证电子束和播种电子束的辐射发射。研究了径向尺寸失配和错向离轴注入对见证光束动力学的影响，以及相关BR的光谱特征。这些非理想电子注入在实验中很可能发生。对质子自调制阶段也进行了深入的研究，包括种子电子束动力学及其BR。作为发射粒子的足迹，BR可以提供有关光束动力学的有价值的信息。本文还讨论了在AWAKE Run 2实验中实施betatron诊断的一些实际挑战。
The oscillating relativistic electrons in the accelerating/focusing wakefields of plasma accelerators emit electromagnetic radiation known as betatron radiation (BR). The proton-driven plasma wakefield acceleration has been demonstrated in the Advanced Wakefield Experiment (AWAKE) at CERN; however, its accompanying radiation emission is less explored compared with those in the laser- and electron beam-driven plasma accelerators. In this paper, a detailed simulation study of BR in the AWAKE is presented. Considering the new set-up of the AWAKE Run 2 (2021–), the radiation emission from both the witness electron beam and the seeding electron beam is investigated using particle-in-cell simulations. The influence of radial size mismatch and misaligned off-axis injection on the witness beam dynamics, as well as the spectral features of the relevant BR are studied. These non-ideal electron injections are likely to occur in experiment. The proton self-modulation stage is also investigated with a close look at the seeding electron beam dynamics and its BR. As a footprint of the emitting particles, BR can provide valuable information about the beam dynamics. Some practical challenges to implement the betatron diagnostic in the AWAKE Run 2 experiment are also addressed.
