Low Energy Gamma Ray Imager
Description
LEGRI was proposed in response to the Spanish Instituto Nacional de Technicas Aerospaciales (INTA) 1993 call for proposals for the first MINISAT mission (MSAT1). The aim of the mission was the demonstration of the technological feasibility of the construction of new generation gamma-ray telescopes, optimized for low energy (10-100 keV) astronomy, using 80 HgI2 detectors and 20 CZT pixels, The Group was involved in developing the detectors. This material provides an excellent response in the 10-100 keV range, with the best presently achieved efficiency/volume ratio. The 10-100 keV region contains unique, not fully explored, astrophysical information regarding nuclear excitation processes, radioactivity, cyclotron emission and absorption processes. http://www.sr.bham.ac.uk/instrument/legri.html |
