Paper Abstract

The SODART x-ray telescope includes an objective crystal spectrometer (OXS) providing a high energy resolving power by Bragg reflection upon crystals. To cover a wide energy range, 3 types of natural crystals, and a Co/C multilayer structure upon Si are used in the ranges 5-11 keV, 2-5 keV, 0.5-1.2 keV, and 0.16-0.42 keV. All types of crystal besides Si being an ideal crystal have been calibrated individually and after gluing onto the Bragg panel. The x-ray calibration procedures and result are discussed below. A ray-tracing program using the OXS calibration data and simulating the x- ray photon reflection on the mentioned crystals and the multilayers has been developed and is described also.
