Paper Abstract

X-ray scattering from a lithium disc and Bragg reflection from a mosaic graphite crystal can be exploited to measure the linear polarization of radiation emitted from cosmic x-ray sources. The sensitivity is greatly enhanced if these polarimeters are placed at the focus of an x-ray telescope. Such devices form two of the three components of the Stellar X-Ray Polarimeter experiment scheduled to fly on the SPECTRUM-X-Gamma mission. The experiment will reside at the focus of one of the SODART x-ray telescopes. We describe the expected on-axis performance of these two components of the Stellar X-Ray Polarimeter experiment based on detailed Monte-Carlo simulation:;. We also discuss various systematic effects, both external and internal to the experiment, that must be considered in order to properly design and utilize the experiment.
