Abstract
We propose to detect the first antihydrogen atoms.The integrated luminosity expected in 1994 of 200 pb-1 for pp annihilation in the E760 hydrogen gas target will produce a sample of 10 3 anti hydrogen atoms.These atoms exit the accumulator in a low emittance, neutral beam which will be detected by an apparatus set up in the gap between the accumulator and debuncher rings.We believe the anti hydrogen can be detected with essentially unit efficiency and zero background; the total cost of the project is roughly $300K.The proponents expect to share costs.We request only a few shifts of protons to make a hydrogen beam with which to calibrate our apparatus, but the experiment is otherwise wholly parasitic on E760 and needs no new beam time.
