An X-ray polarimeter for hard X-ray optics [PDF]

, 2006
Development of multi-layer optics makes feasible the use of X-ray telescope at energy up to 60-80 keV: in this paper we discuss the extension of photoelectric polarimeter based on Micro Pattern Gas Chamber to high energy X-rays.

In situ X-ray area detector flat-field correction at an operating photon energy without flat illumination

Journal of Synchrotron Radiation, 2023
Flat-field calibration of X-ray area detectors is a challenge due to the inability to generate an X-ray flat-field at the selected photon energy the beamline operates at, which has a strong influence on the measurement behavior of the detector.
