Systematic studies for AWAKE Run 2

AWAKE是世界上第一个质子驱动等离子体韦克菲尔德加速实验。它利用来自CERN SPS的400 GeV质子聚束作为驱动束，激发振幅约为GV/m的等离子体韦克菲尔德（比传统加速器高几个数量级），并在10 m长、密度为（1-10）× 10 ~（14）cm ~（-3）的等离子体中将外部注入的10-20 MeV电子聚束加速到几个GeV。目前的AWAKE实验，所谓的运行1，最近取得了重大突破，并证明了稳定和可重复的种子自调制不稳定性（SSM）的长质子束，并成功地加速电子束到2 GeV在一个单一的加速阶段。这种新型的加速技术将为未来紧凑型机器走向能源前沿铺平道路。在AWAKE Run 1取得巨大成功的基础上，Run 2（AWAKE升级计划）旨在为未来应用提供高质量的电子束。对于这个项目，学生将由来自曼彻斯特大学，斯特拉斯克莱德大学和利物浦大学的经验丰富的科学家共同监督，他将在那里注册博士学位。他将在理解电子播种不稳定性，电子注入，捕获和加速过程中发挥主导作用。此外，他将致力于研究新型仪器，以充分表征AWAKE光束。学生将协助数据采集和分析实验数据，交叉检查分析模型和模拟结果，并进一步优化实验装置。研究结果对进一步的AWAKE实验设计具有重要的指导意义。他或她还将出席AWAKE协作会议，并在重要的国际会议和研讨会上报告成果。

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.
