Abstract

The Low Energy Gamma Ray Imager (LEGRI) will be one of the three instruments carried by the first MINISAT mission. LEGRI aims to demonstrate the technological feasibility of a new generation of low energy gamma-ray telescopes with imaging, medium resolution spectroscopy and high continuum sensitivity in the 20-200 keV spectral region, based on HgI2 solid state detector technology.

The data supplied by LEGRI will allow us to investigate HgI2 detectors in astrophysics by examining semiconductor stability, radiation damage and survival capability under space conditions. Furthermore, LEGRI will provide a good scientific output in the very interesting low energy γ-ray/hard X-ray domain.

LEGRI was accepted by the MINISAT consortium in March 1993. The delivery is scheduled by September 1995 and the MINISAT-01 launch at the mid of 1996 with a nominal life of 2 years.
