X-ray polarimetry with phase plates

Review of Scientific Instruments, 1995
Diamond crystals were used as quarter-wave plates (QWPs) and half-wave plates (HWPs) to produce and completely analyze circular and vertical linear polarization of monochromatic x rays from an undulator source (ID10) at the European Synchrotron Radiation Facility.

Hard x-ray polarimetry with EXIST

SPIE Proceedings, 2005
The Energetic X-ray Survey Telesccope (EXIST) is under study for the propsed Black Hole Finder Probe, one of the three Einstein Probe missions in NASA's proposed Beyond Einstein Program. EXIST would have the capability to survey the full sky at 5-600 keV and enable black holes to be surveyed and studied on all scales.

Astrophysical motivation for X-ray polarimetry

Advances in Space Research, 2004
Abstract In this paper I will review the motivation for measuring polarization in the X-ray band from astrophysical sources. Emission models designed to reproduce X-ray spectra can be tested using polarization, and polarization detected in other wavelength bands makes clear predictions as to the X-ray polarization.

Programs of X-ray polarimetry in Italy

2010
Programs of X-ray polarimetry in Italy arise from the convergence of a long experience of X-ray astronomy missions with an outstanding tradition in development of radiation detectors. The gas pixel detector in the focus of X-ray optics can perform angular-resolved polarimetry with a breakthrough improvement in sensitivity, even with a moderate ...
