Paper Abstract

The Objective Crystal Spectrometer (OXS) is part of the SODART X-ray telescope onboard the future SPECTRUM-RONTGEN-GAMMA (SRG) mission. The SODART-OXS energy resolution is compared with those of the gratings of the XMM-NEWTON and CHANDRA telescopes. It is shown that for the high-energy region (2 - 10 keV) SODART-OXS has a substantially better energy resolution (up to 1 order of magnitude). However, the Bragg reflection principle of OXS leads to small photon numbers to be registrated in the detectors. Therefore, a careful choice of observation time and other parameters is necessary. We describe software including a complete ray-tracing procedure which simulates a whole SODART-OXS observation cycle to support the potential observer in his experiment planning. Presently, the software is limited to point sources.
