Stripping of X-ray bremsstrahlung spectra up to 300 kVp on a desk type computer

Abstract

The direct result of a spectrometric measurement is a pulse height distribution. In the energy region up to 300 keV, 3 corrections are needed to get the photon spectrum: corrections for K-escape, Compton scattering and inefficient photon absorption. A simple stripping procedure is described which may be implemented on a desk type computer. All data necessary are explained or may be derived from the measurement of very heavily filtered X-ray spectra. The accuracy of the procedure is better than .+-. 5% of the peak value. Results are compared with a more detailed stripping procedure based on Monte Carlo calculated data.
