gas pixel detector

(GPD)
(type of X-ray imager sensitive to polarization)

A gas pixel detector (GPD) is a type of single-chip X-ray imager that is sensitive to polarization of X-ray photons striking a gas ionize gas molecules, and the electrons are detected using a gas electron multiplier (GEM), a type of electron sensor used in particle physics experiments.
