Dr Maxwell works for the Swansea group on the ALPHA antihydrogen physics experiment at CERN. He did his Ph.D. in the group of Charles Adams at Durham University before starting with Swansea in 2013. In Durham he worked on an experiment involving the storage of photons in laser-cooled, optically trapped atoms. At CERN, one of his main areas of research is a development project which aims to cool positrons using laser-cooled ions. He is also part of the team responsible for ALPHA’s superconducting magnet and cryostat control systems.
