The gas pixel detector as an x-ray photoelectric polarimeter with a large field of view
The Gas Pixel Detector (GPD) is a new generation device which, thanks to its 50 μm pixels, is capable of imaging the photoelectrons tracks produced by photoelectric absorption in a gas. Since the direction of emission of the photoelectrons is strongly correlated with the direction of polarization of the absorbed …
