The study of astronomical objects using electromagnetic radiation involves four basic
observational approaches: imaging, spectroscopy, photometry (accurate counting of the …

The performance of the Time Projection Chamber (TPC) polarimeter for the Polarimeter for
Relativistic Astrophysical X-ray Sources (PRAXyS) Small Explorer was evaluated using …

X-ray polarimetry in astronomy has not been exploited well, despite its importance. The
recent innovation of instruments is changing this situation. We focus on a complementary …

ABSTRACT X-rays are particularly suited to probing the physics of extreme objects.
However, despite the enormous improvements of X-ray astronomy in imaging, spectroscopy …

Polarization properties of parametric x radiation (PXR) produced by E 0= 80.5 MeV electrons
interacting with a 13 μ m thick silicon crystal have been investigated. The direction and the …

The New Hard X-Ray Imaging and Polarimetric Mission makes a synergic use of Hard X-
Ray Imaging, Spectroscopy and Polarimetry, as independent diagnostic of the same …

The regular array of pixels in a silicon Charge Coupled Device (CCD) may be used to
measure photoelectron emission directions following the absorption of high energy X-rays …

The polarisation of X-ray photons can be determined by measuring the direction of emission
of a K-shell photoelectron. Effective exploitation of this effect below 10keV would allow the …

MOS charge coupled devices (CCDs) have been under development for use as X-ray
detectors for Astronomy for over 12 years. In this time many improvements have been …

We have developed a new phoswich detector consisting of an NE213 liquid scintillator
surrounded by an NE115 plastic scintillator to measure high energy neutron spectra …
