X-ray energy spectroscopy - calibration of the X-ray energy detector

Various metal samples are subjected to polychromatic X-rays. The resulting fluorescence radiation is analysed with the aid of a semiconductor detector and a multi-channel analyser. The maxima of intensity of the corresponding characteristic X-ray lines are determined. The predefined energy values of the characteristic lines and channels of the multichannel analyser that must be assigned in turn result in a calibration of the semiconductor energy detector.
