Paper Abstract

The feasibility of a large volume liquid xenon time projection chamber (LXe-TPC) for three- dimensional imaging and spectroscopy of cosmic gamma-ray sources, was tested with a 3.5 liter prototype. The observation of induction signals produced by MeV gamma rays in liquid xenon is reported, with a good signal-to-noise ratio. The results represent the first experimental demonstration with a liquid xenon ionization chamber of a non-destructive read- out of the electron image produced by point-like charges, using a sense wire configuration of the type originally proposed in 1970 by Gatti et al. An energy resolution as good as that previously measured by us with millimeter size chambers, was achieved with the large prototype of 4.4 cm drift gap.
