| Description | Properties of antihydrogen measured including gravity and charge properties. This antimatter has been isolated and measured including quantum transitions The aim is continue the work in future with further grants, The aim will be to study low lying quantum levels. The study of the 1S to 2S transition was the top priority towards the end of 2016, with evidence seen for the resonance.. These findings are fundamental to the study of how matter and antimatter may differ. Spectroscopic results are now available for low lying transitions which allow a direct comparison with hydrogen. Our work has proven to be of interest to a wide community within academia. Directly, there are close to 300 scientists now working on antihydrogen and related fields. None of this would have been possible without the pioneering efforts of some of the investigators on this proposal. Furthermore, the new ELENA facility, a significant expansion to CERN's existing low energy antiproton capability that will both enlarge the antiproton community and extend its operation for at least two more decades, has emerged due, primarily, to the success of the antihydrogen programme at CERN - with ALPHA at the forefront. |
| Exploitation Route | Properties of antimatter are of interest to many other scientists and our publications are regularly featured in both the scientific and popular press internationally. Public interest in fundamental science, including antimatter, remains high and we hope that our feature in the 2016 Royal Society Summer Science Exhibition will contribute to this trend. Research into antimatter is also an ideal topic to train the next generation of researchers and shall will be taken forward through national and international training initiatives. |

| Description | Studies into antimatter particles are of wide interest as they a fundamental and often covered in science fiction films and series; this creates a large public interest in any new findings involving antimatter particles. Our results have been communicated through schools talks, UG lectures, open days, radio and television interviews and have helped raise more awareness of the results to date and the challenges that still are ahead. |
