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.
