Abstract
The purpose of this article is to describe a new methodology for analyzing x-ray transmission. This new technique is called the multi-energy method and is a generalized application of traditional dual-energy methods. This method can be used with broad or line spectra, with photons or other particle and on a large energy range e.g. for photons from 20 keV to higher than 10 MeV. The application of this method in the range 20 to 150 keV with Bremsstrahlung spectra is very fast and allows a precision better than 0.5% on the coefficient of attenuation of photons over a large atomic number range (1 to say 40) and over a large thickness range (< 20 g/cm2). This method, described in the article, protected by two international patents, is applied point by point in the explosive device detection system of Heimann Systems, commercially available under the name of XCalibur.
