  ABSTRACT: The Tracking and Imaging Gamma-Ray Experiment (TIGRE) uses multilayers of silicon strip detectors both as a gamma-ray converter and to track Compton recoil electrons and positron-electron pairs. The direction and energy of the Compton scattered gamma ray and pair particles are measured with arrays of small CsI(Tl)-photodiode detectors. With a large π-steradian field-of-view, the prototype instrument described is sensitive to gamma rays from 0.3 to 100 MeV with a typical energy resolution of 3% (FWHM) and a 1-σ angular resolution of 120 arc min, at 2 MeV. It has a high absolute detection efficiency of 8% over the full energy range. The telescope is described and Monte Carlo calculations are presented

With a large π-steradian field-of-view, TIGRE is sensitive to gamma rays from 0.3 to 100 MeV with a typical energy resolution of 4% (FWHM) and a 1σ angular resolution of 120 arc min. at 2 MeV. The instrument has a high absolute detection efficiency of 8% over the full energy range. The telescope is described and Monte Carlo calculations presented
