Behind every big experiment, there is a lot of theory and many years of scientific research. Especially, when you want to make a measurement that no one else has made before. The ALPHA members have collected some of the most important theoretical basics of what our experiments lean on. We use them every day in our work and would like to show you some of it!
- For more about Antimatter in general, have a look at the CERN Antimatter page
- Good descriptions of 'How ALPHA works' in detail can be found in the publication section on our website
- Particularly appropriate for students and non-physicists are Cold Antihydrogen: a new frontier in fundamental physics, Antihydrogen for precision tests in physics and Antihydrogen in a bottle
- For experts, a general overview of many of the important aspects can be found in Search for Trapped Antihydrogen
On February 19, 2020, ALPHA published the first investigation of the fine structure of Antihydrogen.
In 2018 the ALPHA Experiment was expanded with the addition of ALPHA-g. Look at timelapse videos to see the massive changes, from installation to beamline!
The ALPHA collaboration has for the first time observed single-photon excitation of antihydrogen atoms from the ground (1S) state to the 2P state using 121nm pulsed laser light - the so-called lyman-alpha line of the Lyman series.
