Abstract: The ALPHA experiment performs both spectroscopic and gravitational measurements on antihydrogen. Apparatus can trap only about one atom at a time! All proposed measurements are difficult to perform on a single (anti-) atom. Proposal: Increase the number of antihydrogen atoms available to experiments by cooling positrons as they bind to antiprotons. Positrons in a magnetic field cool via spontaneous emission of cyclotron radiation.
