The liquid-xenon Compton telescope - A new technique for gamma-ray astronomyWe propose a new technique for gamma-ray astronomy in the difficult but important energy decade from 0.3 to 3.0 MeV. Cosmic gamma rays Compton scatter in a liquid-xenon wire proportional chamber recently developed at Lawrence Berkeley Laboratory (Derenzo, et al., 1972; Muller, et al., 1971) and then are totally absorbed in a second chamber. The energy and position of each interaction is recorded for each gamma ray. This information determines a circle on the celestial sphere which must intersect the source position. A localized source of gamma-rays would show itself as the intersection of many such circles. We expect to locate sources to a fraction of a square degree in a balloon-borne sky survey experiment using an instrument with a one steradian acceptance.
