Abstract

The efficiency of an ultra thin windowed Si(Li) detector has been determined experimentally in the photon energy range of 0.28-22.1 keV at the Debrecen scanning nuclear microprobe facility. The calibration technique was based on the measurement of thick targets made from pure elements and chemical compounds by PIXE technique. Characteristic X-ray spectra were fitted and PIXE cross-sections were calculated by the new version of the PIXEKLM program package. The efficiency function was determined by fitting the detector parameters in order to minimize the difference between the measured and calculated efficiency values. The accuracy of the method is estimated to be 20-10% in the 0.28-1 keV energy range and 10-5% above 1 keV. An overview of theoretical and experimental aspects of the efficiency calibration procedure will be presented.
