Abstract A large area (400 cm2) low background X-ray telescope consisting of four collimated NaI/CsI scintillator phoswich detectors (each 100 cm2) was built and successfully flown several times during 1980–1984. The phoswich configuration enables one to eliminate X-ray background produced by high energy atmospheric and cosmic gamma-rays. Combined with large area, small field of view (5° × 5°) and large exposure time that was possible due to an on-board telescope pointing programmer, for the 20 – 120 Kev energy range, 3σ sensitivity achieved was 5 × 10−6 photon/cm2 sec Kev for exposure time of 104 sec at observational altitude of 4 g/cm2. The Instrument characteristics, relevant details on pointing system, detector system, associated electronics and telemetry and in-flight performance in 1983 and 1984 are presented.
