About the Role

STFC’s Accelerator Science and Technology Centre (ASTeC) mission is to build the ‘Big Science’ facilities of the future; we design, build and operate particle accelerators and make major contributions to many of the biggest projects in the world today. Based at Daresbury Laboratory, we work with high-profile national and international partners that include the Cockcroft Institute. STFC is part of UKRI, the UK's national organisation for research; we encourage our staff to undertake world-leading work in a diverse and inclusive environment that supports work-life balance. 

Some of ASTeC's key contributions to international accelerator projects are in the field of Superconducting Radio Frequency (SRF) technology. The main responsibility of the Cryogenics Engineer will be to assist in the development of cryogenic systems which are used in these world-class projects.   

Current high-profile projects include Fermilab’s Proton Improvement Plan Phase 2 (PIP-II), ESS High Beta Cavities, and the High Luminosity upgrade of the Large Hadron Collider at CERN (HiLumi LHC).

Development of Future Opportunities

In addition to contributing to live projects, the Cryogenics Engineer will also support the department in drafting proposals for future work.

ASTeC is a key collaborator in several national and international projects and the department is also engaged in the development of underpinning technologies for SRF thin films and superconducting magnets, along with their associated cryogenic test infrastructure, which all require us to maintain and develop a very strong skill base in cryogenics.
