The Imaging X-ray Polarimetry Explorer (IXPE): technical overview III [PDF]

open access: yes, 2020
IXPE, the Imaging X-ray Polarimetry Explorer, is a NASA SMEX mission with an important contribution of ASI that will be launched with a Falcon 9 in 2021 and will reopen the window of X-ray polarimetry after more than 40 years.

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.

Probing Magnetic Fields and Acceleration Mechanisms in Blazar Jets with X-ray Polarimetry

open access: yesGalaxies, 2021
X-ray polarimetry promises us an unprecedented look at the structure of magnetic fields and on the processes at the base of acceleration of particles up to ultrarelativistic energies in relativistic jets.

Photoelectric Polarimetry and the Gas Pixel Detector Yesterday, Today and Tomorrow

open access: yesGalaxies, 2018
Since the very beginning of X-ray Astronomy, polarimetry has been suggested as a tool of diagnostics, of great potentiality. While almost all measurements of X-rays were based on detectors using the photoelectric effect, the first attempt to perform ...

The Imaging X-Ray Polarimetry Explorer (IXPE): Technical Overview II [PDF]

open access: yes, 2019
The Imaging X-ray Polarimetry Explorer (IXPE) will add polarization to the properties (time, energy, and position) observed in x-ray astronomy. A NASA Astrophysics Small Explorer (SMEX) in partnership with the Italian Space Agency (ASI), IXPE will ...
