N2 - We report on Monte Carlo studies of the hard X-ray polarimeter X-Calibur. The polarimeter will be used in the focal plane of a grazing incidence hard X-ray telescope. It combines a low-Z Compton scatterer with a high-Z Cadmium Zinc Telluride (CZT) detector assembly to measure the polarization of 10 keV 80 keV X-rays. X-Calibur makes use of the fact that polarized photons Compton scatter preferentially perpendicular to the electric field orientation. In contrast of competing designs which use only a small fraction of the incoming X-rays, X-Calibur achieves a high detection efficiency of order unity. In this contributions, we discuss a Monte Carlo study which compares X-Calibur's polarimeteric performance achieved using different scattering materials (Scintillator, Be, LiH, Li), and calculate the sensitivity of X-Calibur when used with different balloon-borne and space-borne mirror assemblies.
