在达雷斯伯里实验室的等离子体加速器A装置上建立了等离子体加速器研究站（PARS），用于研究电子驱动等离子体韦克菲尔德加速的关键问题。本文分析了束流驱动等离子体韦克菲尔德加速的准非线性区。用二维粒子模拟程序模拟了不同入射光束设置下的韦克菲尔德。对于单个驱动光束，可以实现高达3GV/m的加速梯度。对于两个聚束加速的情况，模拟表明，见证聚束可以在10-50 cm长的等离子体单元中实现显著的能量增益。
A plasma accelerator research station (PARS) has been proposed to study the key issues in electron driven plasma wakefield acceleration at CLARA facility in Daresbury Laboratory. In this paper, the quasi-nonlinear regime of beam driven plasma wakefield acceleration is analysed. The wakefield excited by various CLARA beam settings are simulated by using a 2D particle-in-cell (PIC) code. For a single drive beam, an accelerating gradient up to 3 GV/m can be achieved. For a two bunch acceleration scenario, simulation shows that a witness bunch can achieve a significant energy gain in a 10–50 cm long plasma cell.
