The Oriented Scintillation Spectrometer Experiment Instrument Description

Abstract

The Oriented Scintillation Spectrometer Experiment (OSSE) on the Arthur Holly Compton Gamma Ray Observatory satellite uses four actively- shielded NaI(Tl)- CsI (Na) phoswich detectors to provide gamma-ray line and continuum detection capability in the 0.05 - 10 MeV energy range. The instrument includes secondary capabilities for gamma-ray and neutron detection between 10 and 250 MeV. The detectors have 3.8 degrees x 11.4 degrees (FWHM) fields-of-view defined by tungsten collimators. Each detector has an independent, single-axis orientation system which permits offset pointing from the spacecraft Z-axis for background measurements and multi-target observations. The instrument, its calibration and performance are described.
