About the Project

In collaboration with our partners in the Cockcroft Institute of Accelerator Science and Technology, the accelerator physics group in the department of physics at Lancaster University has a PhD studentship available for October 2022.

Accelerator physicists work at the intersection between multiple disciplines, developing the tools to address fundamental questions about the nature of the world: from particle physics to biology. Generating particle beams with higher energies or higher intensities than those available today requires innovations which range from the highly theoretical to hands-on engineering and technical work. This project gives you the opportunity to become involved in research to produce intense particle beams of high power with a wide range of applications.

To date, major accelerator-based scientific facilities have mostly taken the form of ‘synchrotrons’ (e.g. the Large Hadron Collider) in which beams circulate or ‘single-pass’ linear accelerators (e.g. European XFEL) in which beams pass through the accelerator only once. However, these solutions may not be optimal. New developments in particle beam dynamics and the maturity of superconducting technology, gives us an intriguing opportunity to forge a step-change in accelerator performance through the deployment of high energy ‘multiple-pass recirculating linacs’. When correctly configured such devices promise for the first time the simultaneous production of high ‘brightness’ beams at high power. This will have far reaching implications for particle and nuclear physics when implemented as a collider, and for the life sciences and industry when implemented as a ‘Free-Electron Laser’. The 2020 European Strategy for Particle Physics specifically calls for R&D into Energy Recovery Linacs and the successful candidate will join this global effort.

This PhD project will entail the simulation and optimisation of recirculating linac (linear accelerator) architectures for three proposed accelerator facilities: the CERN-based Large Hadron Electron Collider (LHeC), the electron cooler for the US-based Electron-Ion Collider (EIC), and a potential UK-based monoenergetic gamma-ray source with industrial and fundamental physics applications. The emphasis will be on the common design principles of accelerators to address the needs of this wide range of applications. This will give you ample opportunities to gain the experience to pursue an ongoing career within the particle accelerator field, if you choose.

You will have or expect to obtain a first or upper second-class degree or equivalent (e.g. MPhys or MSci) in physics. Experience of computer simulations and/or accelerator physics is not essential as all training will be provided, indeed we encourage applications from all good candidates with degree level experience in any aspect of physics. You will primarily be based at the Cockcroft Institute in Daresbury Laboratory, although a period of work at an overseas laboratory may be possible.

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 international 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 over 150 people.
