Abstract: The design and estimated performance of a balloon-borne hard X-ray polarimeter called HX-POL is reported. The experiment uses a combination of Si and Cadmium Zinc Telluride (CZT) detectors to measure the polarization of 50–500 keV X-rays through the dependence of the angular distribution of Compton scattered photons on the polarization direction. On a 15 to 30-day balloon flight, HX-POL would allow one to measure the polarization of bright Crab-like sources for polarization degrees down to a few %. Hard X-ray polarization measurements provide unique venues for the study of particle acceleration processes by compact objects and relativistic outflows.
