How ALPHA works
Components of ALPHA
This section descibes how the most important components of ALPHA work. These are: the Penning trap, which holds the positrons and antiprotons before we use them to make antihydrogen, the atom trap, which traps and holds the antihydrogen atoms, and the annihilation vertex imaging detector, which detects the antihydrogen atoms when we allow them to annihilate and can find the point at which they annihilated.
(Note: this section is still incomplete, we'll be adding more here)
Good descriptions of how ALPHA works con be found in the publications section.
Particularly appropriate for students and non-physicists are Cold antihydrogen: a new frontier in fundamental physics and Antihydrogen for precision tests in physics.
For experts, a general overview of many of the important aspects can be found in Search for Trapped Antihydrogen.
