Title:
DETECTOR FOR X-RAY FLUORESCENCE
Document Type and Number:
WIPO Patent Application WO/2019/080035
Kind Code:
A1
Abstract:
A detector (100) comprises: a plurality of pixels (150), each pixel (150) configured to count numbers of X-ray photons incident thereon whose energy falls in a plurality of bins, within a period of time; an X-ray absorption layer (110); wherein the X-ray absorption layer (110) comprises an electrical contact (119B) within each of the pixels (150), and a focusing electrode (1101) surrounding the electrical contact (119B) and configured to direct to the electrical contact (119B) charge carriers generated by an X-ray photon incident within confines of the focusing electrodes (1101); and wherein the detector (100) is configured to add the numbers of X-ray photons for the bins of the same energy range counted by all the pixels (150).
