About The University

Swansea University is a research-led university that has been making a difference since 1920. The University community thrives on exploration and discovery and offers the right balance of excellent teaching and research, matched by an enviable quality of life.

Our stunning waterfront campuses and multicultural community make us a desirable workplace for colleagues from around the world. Our reward and benefits, and ways of working enable those who join us to have enriching careers, matched by an excellent work-life balance.

About The Role

The ALPHA collaboration at CERN synthesises and traps antihydrogen for precision tests of fundamental symmetry. The collaboration is world leading in precision spectroscopy and gravitational studies of antihydrogen. Following a major upgrade to the frequency metrology instrumentation in ALPHA, the aim is now to achieve or surpass the precision of spectroscopy in ordinary hydrogen. Swansea University is a founding member and a major stakeholder in the collaboration.

The successful candidate will join the Swansea team at CERN and will become a full member of the ALPHA collaboration. The group has three permanent academic staff members, four post-doctoral staff and a varying number of PhD students actively contributing to the ALPHA project at CERN.

We require the successful candidate to have a PhD in experimental physics. Experience in relevant sub-fields (e.g. laser physics, laser cooling, frequency metrology, trapped charged particles or atoms) or with some of the techniques we use (for instance cryogenics, ultra-high vacuum and Labview) will be appreciated.  

Equality, Diversity & Inclusion

The University is committed to supporting and promoting equality and diversity in all its practices and activities. We aim to establish an inclusive environment and welcome diverse applications from the following protected characteristics: age, disability, gender reassignment, marriage and civil partnership, pregnancy and maternity, race (including colour, nationality, ethnic and national origin), religion or belief, sex, sexual orientation.
