Abstract

The phoswich detection system (PDS) is one of the four narrow field experiments on board the SAX satellite. The PDS will be dedicated to deep temporal and spectral studies of celestial x- ray sources in the 15 - 300 keV energy band. It also includes a gamma-ray burst monitor. The PDS detector is composed of 4 actively shielded NaI(Tl)/CsI(Na) phoswich scintillators with a total geometric area of 795 cm2 and a field of view of 1.3 degrees (FWHM). In this paper we report results of the experiment on-ground calibrations before its integration in the spacecraft and the expected experiment in-flight performance.© (1995) COPYRIGHT SPIE--The International Society for Optical Engineering.
