X-ray telescope-spectrometer, installed on board the space station 'Salyut-4'
Abstract
The Salyut-4 X-ray instrument consists of four gas flow proportional counters, three of which have a total detection surface of 450 sq cm in the energy range 2-10 keV, and one of which has an effective surface of 37 sq cm for the range 0.2-2 keV. The instrumentation also includes optical sensors which are mounted on the outside of the station together with the X-ray detectors, and power supply and measurement units which are inside the station. Ground based calibration of the detectors is considered along with in-flight operation in three modes: inertial orientation, orbital orientation, and survey. Observation of the transient X-ray source A0620-00 is discussed.
