A balloon-borne Compton telescope is described that makes it possible to perform astronomical gamma-ray observations in the energy range 1-20 MeV. The telescope comprises an array of organic liquid scintillators (NE 213) in the upper detector and NaI(T1) in the lower detector. Background radiation is suppressed by means of time-of-flight and pulse-shape-discrimination techniques and sophisticated event selection criteria. The properties of the telescope determined from calibration measurements, Monte Carlo calculations, and data from two balloon flights are described. It is noted that the telescope has imaging properties within its field of view of 40 deg to 50 deg FWHM. At 2.75 MeV, its angular resolution is 8.5 deg FWHM, and its energy resolution is approximately 10% FWHM. A method is described through which the image of a celestial gamma-ray source within the field of view can be constructed in the presence of the gamma-ray background radiation at high balloon altitudes.
