Plasma accelerators have made tremendous progress in the last few decades since the inception of the idea from Tajima and Dawson. Nowadays, laser wakefield accelerators (LWFA) could achieve multi-GeV level, mono-energetic electrons through millimeter to centimeter plasma cells. Electron beam driven plasma wakefield acceleration (PWFA) has demonstrated energy doubling for an ultra relativistic 42 GeV electron beam in a meter long plasma structure and recently realized the high efficiency beam acceleration at SLAC FACET facility. The accelerating gradients measured in these experiments can be in the range of 10-100 GeV/m, which are 3-4 orders of magnitude larger than that in todays' conventional RF-based particle accelerators. Since plasma wakefield accelerators hold great promise to miniature the future energy frontier machines, the research on the key issues, e.g. the ultrahigh accelerating gradients, plasma lens (plasma focusing), high transformer ratio, plasma instabilities of the plasma wakefield accelerators are critical for the new generation facility such as compact light sources and colliders based on this novel acceleration scheme. Working together with colleagues from ASTeC and the University of Strathclyde, we are currently preparing for the first UK based beam driven plasma wakefield acceleration experiment at Darebury laboratory using the VELA/CLARA beam. The first experiment will demonstrate the plasma lens strong focusing effect. The follow-up experiment will investigate other key issues as above-mentioned.The study will include full modelling of beam-plasma interaction, engineering design and manufacture of plasma cell, commissioning of the experimental facility and analysing the experimental data.

自从田岛和道森提出这个想法以来，等离子体加速器在过去的几十年里取得了巨大的进步。如今，激光尾场加速器（LWFA）可以通过毫米到厘米的等离子体细胞实现多GeV级的单能电子。电子束驱动等离子体尾场加速 (PWFA) 已证明在一米长的等离子体结构中超相对论 42 GeV 电子束的能量倍增，并且最近在 SLAC FACET 设施实现了高效束流加速。这些实验中测得的加速梯度可在 10-100 GeV/m 范围内，比当今传统的基于射频的粒子加速器大 3-4 个数量级。由于等离子体尾场加速器在微型化未来能源前沿机器方面有着巨大的前景，因此对关键问题的研究，例如等离子体尾场加速器的超高加速梯度、等离子体透镜（等离子体聚焦）、高变压器比、等离子体不稳定性对于基于这种新颖加速方案的紧凑型光源和对撞机等新一代设施至关重要。我们目前正在与 ASTeC 和斯特拉斯克莱德大学的同事合作，准备在 Darebury 实验室使用 VELA/CLARA 光束进行英国首个光束驱动等离子体尾场加速实验。第一个实验将展示等离子透镜强大的聚焦效果。后续实验将研究上述其他关键问题。研究内容包括束-等离子体相互作用的完整建模、等离子体电池的工程设计和制造、实验装置的调试以及实验数据分析。
