摘要：

A high resolution telescope for imaging cosmic gamma-ray sources in the MeV region, with an angular resolution better than 0.5-degrees is being developed as balloon-borne payload. The instrument consists of a 3-D liquid xenon TPC as gamma-ray detector, coupled with a coded aperture at a distance of 1 meter. A study of the actual source distribution of the 1.809 MeV line from the decay of Al-26 and the 511 keV positron-electron annihiliation line is among the scientific objectives, along with a search for new gamma-ray sources. The telescope design parameters and expected minimum flux sensitivity to line and continuum radiation are presented. The unique capability of the LXe-TPC as a Compton Polarimeter is also discussed.
