Abstract
A polarimeter utilizing the polarization dependence of x-ray scattering from the low Z metal Lithium will be flown on the SPECTRUM-X-Gamma missionl. The instrument will reside at the focus of one of the SODART x-ray telescopes. An important design consideration is the spurious polarization signature which occurs when unpolarized incident flux is focused a relatively small distance away from the precise axis of symmetry. In this paper we present the results of analytical and Monte-Carlo studies of this effect.
