The LXeCAT instrument for gamma-ray astrophysics.
Abstract
The Liquid Xenon Coded Aperture Telescope (LXeCAT) and its capability to image astrophysical γ-ray sources in the MeV region is described. The γ-ray detector is a Liquid Xenon Time Projection Chamber (LXe-TPC) triggered by the primary scintillation light. Effective background rejection is a direct consequence of the intrinsic three-dimensional imaging capability of the LXe-TPC. Initial results with a 10 liter prototype confirm an energy resolution of 6% FWHM, a position resolution of 1mm RMS and a light triggering efficiency higher than 90% for 1MeV γ-rays.
