Abstract:
It is proposed to fly a high spectral and temporal resolution - "Solar X-Ray Spectrometer (SOXS)" onboard Indian satellite. The SOXS will provide the disk integrated flux in the energy range 2 keV-10 MeV. It is composed of two detector modules - SOXS Low Energy Detector (SLD) and SOXS High Energy Detector (SHD). The SLD consists of state-of-the-art Silicon PIN and Cadmium-Zinc-Telluride detectors to study the energy spectra in 2-30 keV with sub-keV energy and 10 ms temporal resolution. Proposed instrumentation for SLD module consists of front-end electronics, Pulse - height analyser, DC to DC modules, house keeping parameters to monitoring logic and interfacing for SOXS Low Energy Processing Electronics (SLE) to SOXS Common Electronics (SCE). The SLE collects the data from the two detectors and process the data in temporal and spectral modes. The SLE is interfaced with Telemetry and SCE. The salient feature of SLD is real time formulation of spectra in four time intervals as commanded by processing electronics.
