16 October 1995 High-Pressure Gas Scintillation Proportional Counter on SAX and its performance characteristics
Author Affiliations +
The high pressure gas scintillation proportional counter (HPGSPC) is one of the narrow field instruments onboard the Italian Dutch mission for x-ray astronomy SAX. Sensitive in the 4 - 120 keV band the HPGSPC will investigate all categories of astrophysical sources emitting in the not yet well studied hard x-ray domain with a special emphasis on the cyclotron line features that are present in the hard x-ray spectrum of many celestial sources. The on-ground calibration of the flight model of the HPGSPC was carried out at Laben, Italy during October/November 1994. In this paper after describing the flight model of the HPGSPC instrument, we report preliminary results on its spectral capabilities and background rejection efficiency.
