Physics with antihydrogen

Closing date for applications:  applications accepted all year round

Project description:

As the most abundant and simplest element, hydrogen has been studied both theoretically and experimentally to great precision, and our best models predict that equal amounts of matter and antimatter were created at the birth of the Universe. However, very little antimatter, and no naturally occurring source of antihydrogen, can be found today. In an attempt to explain this discrepancy the ALPHA collaboration, based at CERN, create, hold and test antihydrogen for precision comparison to hydrogen (

A successful PhD candidate will be fully integrated into the collaboration at CERN and will have the opportunity to participate in the state-of-the-art research such as development of the laser spectroscopy apparatus that will interrogate the 1S-2S antihydrogen transition, develop a source of low temperature positrons via the use of beryllium-ion laser cooling or investigate antihydrogen formation processes. 

The student will develop highly specialised skills related to antimatter production, it’s uses, charged particle storage and manipulation but also highly transferrable skills admired by industry related to lasers and optics, computer programming, CAD & development, electronics, EM fields, vacuum technology, cryogenics, data and signal analysis to name a few and feature as an author on papers regularly published in high profile journals such as Nature.

This is a non-funded PhD opportunity available through Swansea University College of Science and the Department of Physics. The Student will be based within the ALPHA Collaboration at CERN, Geneva, Switzerland.


Candidates must have a first, upper second class honours or a Masters degree (with Merit), in a relevant discipline. Informal enquiries are welcome by emailing Professor M. Charlton (
