Abstract

The low energy gas scintillation proportional counter (LE-GSPC) is an imaging x-ray spectrometer. It is one of the narrow field instruments on board the SAX satellite and covers the lower energy range from 0.1 to 10 keV. The low energy response of the detector is achieved by using a driftless gas cell and a thin multilayer polyimide foil as entrance window. The overall design of the imaging GSPC for space application is described. Using unit level and system level calibration data, acquired at a synchrotron and a long beam x-ray source, the capabilities both in terms of energy and position resolution are discussed. The overall efficiency of the instrument which includes the mirror's effective area, the entrance windows' transparencies, the detector's efficiency and electronics deadtime are reviewed. Background rejection issues and the experiment's consequent sensitivity to the measurement of cosmic x- ray source spectra are addressed.
