Design and Tests of the Hard X-ray Polarimeter X-Calibur

Design and Tests of the Hard X-ray Polarimeter X-Calibur

X-ray polarimetry promises to give qualitatively new information bout high-energy astrophysical sources, such as binary black hole  systems, micro-quasars, active galactic nuclei, and gamma-ray bursts. We designed, built and tested ahard X-ray polarimeter, X-<em>Calibur</em>, to be used...
