Abstract

The Stellar X-Ray Polarimeter (SXRP) will be the third orbiting stellar x-ray polarimeter, and should provide an order of magnitude increase in polarization sensitivity over its predecessors. The SXRP exploits the polarization dependence of reflection from a graphite Bragg crystal and scattering from a lithium Thomsom scattering target to measure the linear polarization of x-rays from astrophysical sources. In this paper, we review the status of the SXRP instrument.
