| Popis: | The Tracking and Imaging Gamma-Ray Experiment4 (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 ?-steradian field-of-view, the prototype instrument described here is sensitive to gamma rays from 0.3 to 100 MeV with a typical energy resolution of 3% (FWHM) and a 1-? 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 will be described and Monte Carlo calculations will be presented. Measurements with a small desktop instrument are presented elsewhere in this volume. © 1995 IEEE.
