Systematic studies of electron seeding, injection and acceleration in AWAKE Run 2


About This PhD Project

Project Description

A studentship is available from October 2020 on the research on AWAKE (Advanced proton-driven WAKefield Experiment) project at CERN. 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)×1014cm-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. He or she will be taking a leading role in understanding the electron seeding instability, electron injection, trapping and acceleration processes. The research will be supported by extensive theoretical and simulation investigation on beam-plasma interactions, with inputs from AWAKE experimental data. The student will assist in data taking (for accelerated beam) 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.
The applicant will be expected to have a first or upper second class degree in physics or other appropriate qualification. Understanding of electromagnetism and computational physics are desirable but not essential, as a full and extensive postgraduate training will be provided by the Cockcroft Institute.

Potential applicants are encouraged to contact Dr. Guoxing Xia () for more information. This position will remain open until filled.

Funding and eligibility: Upon acceptance of a student, this project will be funded by the Science and Technology Facilities Council for 3.5 years; UK and other EU citizens are eligible to apply. A full package of training and support will be provided by the Cockcroft Institute, and the student will take part in a vibrant accelerator research and education community of around 200 people that includes around 70 postgraduates. An IELTS score of at least 6.5 is required.
