    Status of the development of the imaging proportional counters for the Stellar X-Ray Polarimeter

    The Stellar X-Ray Polarimeter SXRP will be flown at the focus of the SODART X-ray telescope aboard the Russian satellite SPECTRUM-X-Gamma by the end of 1995. Four imaging proportional counters will detect phot...

    The Stellar X-Ray Polarimeter for the SPECTRUM-X-Gamma Mission

    We describe an X-ray polarimeter which will be flown on the SPECTRUM-X-Gamma mission. The instrument exploits three distinct physical processes to measure polarization: Bragg reflection from a graphite crystal...

    A solar flare X-ray polarimeter for the space shuttle

    We have recently built and tested an instrument designed to measure the polarization of the hard (5–30 keV) X-ray emission from solar flares, and thereby to investigate the energy release mechanism and constra...

    Thermal X-ray emission from neutron stars

    The Einstein Observatory (HEAO 2) presents the first realistic opportunity to see a neutron star by observing radiation from its surface. In this review we show that the detection of such thermal radiation or ...

    Upper Limit of the X-ray Polarization of the Crab Nebula

    A rocket-borne X-ray polarimeter was flown to search for polarization in Taurus X-1. Although a result consistent with zero polarization was obtained, the statistics were such that X-ray polarization comparabl...
