AWAKE is the world first proton-driven plasma wakefield acceleration experiment. It utilizes 400 GeV proton bunch from the CERN SPS as the drive beam, excites the plasma wakefield with amplitude of ~ GV/m (which are orders of magnitude higher than conventional accelerators) and accelerates an externally injected 10-20 MeV electron bunch up to several GeVs in a 10 m long plasma with density of (1-10)x1014cm-3. The current AWAKE experiment, so-called Run 1 has recently made great breakthrough and demonstrated stable and reproducible seeded self-modulation instability (SSM) for a long proton bunch and successfully accelerated the electron beam up to 2 GeV in a single stage of acceleration. This novel acceleration technology will pave the way for future compact machines towards the energy frontier.Based on the great success of AWAKE Run 1, Run 2 (the AWAKE upgrade plan) aims for achieving high quality electron beam for future applications. For this project, the student will be co-supervised by experienced scientists from the University of Manchester, University of Strathclyde and University of Liverpool where he will be registered for his PhD. He will be taking a leading role in understanding the electron seeding instability, electron injection, trapping and acceleration processes. In addition, he will contribute to studies into novel instrumentation that will fully characterize the AWAKE beams.The student will assist in data taking and analyze the experimental data and cross check the analytical models and simulation results and further optimize the experiment setup. The research results will have great impact to the further AWAKE experiment design. He or she will also attend the AWAKE Collaboration meetings and report the results at important international conferences and workshops.

AWAKE是世界上第一个质子驱动等离子体尾流场加速实验。它利用来自CERN SPS的400 GeV质子束作为驱动束，以~ GV/m的振幅激发等离子体尾流场（比传统加速器高几个数量级），在10 m长密度为（1-10）x1014cm-3的等离子体中，将外部注入的10-20 MeV电子束加速到几个GeV。目前的AWAKE实验，即Run 1，最近取得了重大突破，证明了长质子束的稳定和可重复的种子自调制不稳定性（SSM），并成功地在单级加速中将电子束加速到2 GeV。这种新颖的加速技术将为未来的紧凑型机器走向能源前沿铺平道路。基于AWAKE Run 1的巨大成功，Run 2 （AWAKE升级计划）旨在为未来的应用实现高质量的电子束。在这个项目中，该学生将由曼彻斯特大学、斯特拉斯克莱德大学和利物浦大学经验丰富的科学家共同指导，他将在利物浦大学注册博士学位。他将在理解电子播种不稳定性、电子注入、俘获和加速过程方面发挥主导作用。此外，他还将为新型仪器的研究做出贡献，这些仪器将充分表征AWAKE光束。协助数据采集和分析实验数据，并对分析模型和仿真结果进行交叉检查，进一步优化实验设置。研究结果将对进一步的AWAKE实验设计产生重要影响。他或她还将参加AWAKE协作会议，并在重要的国际会议和研讨会上报告结果。
