| 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. |
