Description | A large number of high impact papers have been published concerning the detailed spectroscopy of antihydrogen including the 1S-2S transition and hyperfine splitting. Experiments continue to improve the precision. Furthermore, important papers were published about beam transport in low energy beam lines and storage rings. The design of a novel sensor for the characterization of 3D electrostatic field was also published in PRL. |
Exploitation Route | They will be of interest to those interested in fundamental physics. The beam transport framework and low energy instrumentation that has been developed will be of benefit for essentially any low energy ion and antiproton experiment and facility. |
Sectors | Education |
Description | There has been a significant number of public outreach activities, including science exhibitions, school visits and articles in press about the ALPHA findings. This has stimulated a dialogue and discussion about the importance of fundamental research. |
