About this job

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.
