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)
