Abstract: Discusses the production and detection of cold antihydrogen atoms. Mixing of trapped antiprotons and positrons in a cryogenic environment; Direct detection of neutral anti-atoms when they escape the trap and annihilate, producing a characteristic signature in an imaging particle detector.
