AD-5
(Redirected from ALPHA experiment)
The Antihydrogen Laser Physics Apparatus (ALPHA), also known as AD-5, is an experiment designed to trap antihydrogen in a magnetic trap in order to study its atomic spectra. The ultimate goal of the experiment is to test CPT symmetry through comparing the respective spectra of hydrogen and antihydrogen. Scientists taking part in ALPHA include former members of the ATHENA experiment (AD-1), the first to produce cold antihydrogen in 2002.
