SOXS

 Details of SOXS Instrument

   * Solar X-Ray Spectrometer (SOXS) was flown onboard GSAT-2 Indian spacecraft on 8-May-2003.
   * SOXS employs Si and CZT semiconductor devices, which are extremely high resolution and low noise detectors.
   * Detector package is mounted on a Sun Pointing Mechanism with tracking accuracy better than 0.1 degree.
   * Pulse Height (PHA) measurements in 256 channels.
   * System Dead Time- 16 microseconds for Si Pin and 13 microseconds for CZT.
   * Energy window counters.
   * On board calibration using Cd109 Radio isotope.
   * System Health Parameters Monitoring.
   * Onboard selection for Background Rejection (LLD/Threshold).
   * In view of Temperature sensitivity of the detectors, observational interval is < 3 Hrs starting from 04:00 to 06:45 UT.
