X-ray Polarimetry

open access: yes, 2010
Due to the advent of a new generation of detectors, X-ray polarimetry promises to join X-ray imaging, spectroscopy and timing as one of the main observational techniques in high energy astrophysics. This has renewed interest in the field, and indeed several polarimetric missions have recently been proposed.

X-Ray Polarimetry as a Tool to Constrain Orbital Parameters in X-Ray Binaries

open access: yesThe Astrophysical Journal
X-ray binary systems consist of a companion star and a compact object in close orbit. Thanks to their copious X-ray emission, these objects have been studied in detail using X-ray spectroscopy and timing.

X-ray polarimetry and its application to strong-field quantum electrodynamics

open access: yesHigh Power Laser Science and Engineering, 2023
Polarimetry is a highly sensitive method to quantify changes of the polarization state of light when passing through matter and is therefore widely applied in material science.

Broadband soft x-ray polarimetry [PDF]

open access: yesSPIE Proceedings, 2010
We developed an instrument design capable of measuring linear X-ray polarization over a broad-band using conventional spectroscopic optics. A set of multilayer-coated flats reflects the dispersed X-rays to the instrument detectors. The intensity variation with position angle is measured to determine three Stokes parameters: I, Q, and U -- all as a ...

Ultra-high precision x-ray polarimetry with artificial diamond channel cuts at the beam divergence limit

open access: yesPhysical Review Research, 2020
We report on the use of synthetic single-crystal diamonds for high definition x-ray polarimetry. The diamonds are precision mounted to form artificial channel-cut crystals (ACCs). Each ACC supports four consecutive reflections with a scattering angle 2Θ_{

Equalizing the Pixel Response of the Imaging Photoelectric Polarimeter Onboard the IXPE Mission

open access: yesThe Astronomical Journal, 2023
The Gas Pixel Detector is a gas detector, sensitive to the polarization of X-rays, currently flying onboard the Imaging X-ray Polarimetry Explorer (IXPE)—the first observatory dedicated to X-ray polarimetry.
