How ALPHA Works
How ALPHA works
This is for you!
ALPHA is not just one apparatus. The apparatus consists of different sub-elements, which are all produced and maintained by experts from around the world. At CERN we then rebuild these components and make the whole experiment work together.
Different Experiments at ALPHA
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.
