Extract

XRF intensity computations, for polychromatic x-ray sources and multicomponent samples, need a high number of low speed floating-point operations, making them a hard bone for any computer. The evaluations of the Intensity expression require the computation of complex attenuation coefficients. They involve also a spread quantity of atomic data for a high number of elements. And the users need to insert additional information on the experiment, like the excitation-detection geometry or the x-ray tube spectrum, interactively. Personal computers are an optimum target for this kind of application mainly due to the low cost of the computation time and the possibility to display high-resolution graphics. Moreover the increasing power of microprocessors makes it possible to attack hard computations like this on a PC.
