LXeGRIT (Liquid Xenon Gama-Ray Imaging Telescope)

Developed by Columbia University

Balloon launched on 8/25/1997, from Columbia Scientific Balloon Facility, Palestine, Texas, US

Purpose of the flight and payload description

LXeGRIT is a balloon-borne Compton telescope employing a large volume liquid xenon time projection chamber (LXeTPC) as the central gamma-ray detector. It is designed to image gamma rays in the energy range of 200 keV to 20 MeV, with an angular resolution of about 3 degrees (1 sigma) at 2 MeV, within a field-of-view (FOV) of about 1 sr.
