Together our scientists, technologists, engineers, and business support team explore the unknown and turn what they find into work that changes the world around us. Whether it's sending probes into space or finding new ways to treat cancer, everyone here plays a vital role in making a positive difference to society. Come and discover how much you can achieve when you're surrounded by world-leading experts, encouraged to constantly learn and empowered to explore your curiosity.

ISIS is the spallation neutron source located at the Rutherford Appleton Laboratory in the UK. The accelerator facility delivers high intensity proton beams to two target stations to generate neutrons for condensed matter research. Operation and development of the accelerators requires advanced knowledge of beam dynamics and high levels of beam control. The Synchrotron group is looking for an accelerator physicist to join the team to undertake a substantial role in accelerator physics R&D and design work for next generation accelerator facilities, as well as supporting ISIS operations and developments.


  • Lead topical areas of the accelerator physics R&D program, undertake research into high intensity proton beams. Apply results to optimisation of the existing and future machines.
  • Learn how to operate the ISIS accelerator facilities and then join the team in setting up the high intensity beams for each user run. Involvement in experimental studies.
  • Lead topical R&D areas of the ISIS II upgrade accelerator physics project designing new machines.
  • Produce reports, publications, and present work at both internal, external and international events.
  • Willingness to travel to conferences and for collaboration work both within the UK and internationally.
  • To be able to work outside normal hours and be willing to take part in "on call" work as and when required.
  • Work will also involve occasional time in radiation areas requiring the candidate to be a classified radiation worker.

Personal Skills and Attributes


  • Good BSc or MPhys degree in physics
  • PhD in relevant accelerator physics topics, or equivalent expertise
  • Good knowledge of accelerator physics and related basic physics
  • Relevant experience and demonstrated skills on practical or simulation physics R&D projects
  • Good numerical and programming skills
  • A genuine interest and enthusiasm for physics, particularly accelerator physics
  • Be or become a classified radiation worker
  • Willingness to occasionally work overtime or extended hours and to be "on-call" to support ISIS when suitably trained


  • Experience in beam operations and optimization at an accelerator facility
  • Experience with, and responsibility for developing, accelerator physics R&D projects
  • Working knowledge and skills in programming languages: e.g. FORTRAN, Python, C++
  • Experience with beam dynamics, EM simulation and modelling codes
  • Demonstrated skills in experimental work, including real world acquisition of data and its interpretation, beam measurements
  • Knowledge of beam dynamics issues for high intensity hadron beams

STFC imageAt the Science and Technology Facilities Council (STFC), part of UK Research and Innovation (UKRI), research is driven by practical applications and a curiosity to create a world-leading hub of scientific and engineering excellence. Our science and facilities enable researchers to answer fundamental questions about the nature of the universe. Success typically requires long-term strategic investment, international collaboration on a global scale and the capability to push the limits of technology and engineering. To remain internationally competitive in our areas of science and to keep our facilities at the leading edge, we have to develop bespoke technology that cannot be reliably sourced on the open market, for example in detectors and instrumentation, accelerators, specialist engineering, optics and e-infrastructure. These technologies are often also applied to address broader societal and industrial challenges and we actively promote their translation and commercialization.

Why work for us
When you join STFC, you become a key part of one of Europe’s largest research organizations. We are trusted to support, enable, and undertake cutting-edge projects in an amazing diversity of fields that you could be a part of. With access to our world-class facilities, people like you are helping us to drive ground-breaking advances in science, engineering, computing and technology.

  • The Particle Physics Department (PPD) is one of the largest particle physics groups in the UK. We design, construct and operate some of the most sensitive scientific instruments in the world, collaborating with partners in academia, industry and international laboratories such as CERN. We currently work with the ATLAS, CMS, LHCb, DUNE, Hyper-K, T2K, MICE, Lux-Zeplin, DEAP-3600, CERN RD50, Electron Ion Collider and AION collaborations.
  • The National Quantum Computing Centre (NQCC) is a £93m UKRI investment over five years based at the Harwell Campus. This is a strategic element within the overall £1bn, 10-year investment into quantum technologies made by the UK since 2014.

Our benefits

  • 30 days annual leave plus 10.5 public and privilege days.
  • Flexible or hybrid working may be available dependent on role.
  • Defined benefit pension scheme (employer contribution – currently up to 26%).
  • Sport and social groups across campus with access to an on-site gym.
