Monte Carlo simulation of generations of continuous and characteristic X-rays by electron impact

A new Monte Carlo (MC) simulation code has been developed to describe the s pectra of not only continuous X-rays but also characteristic X-rays. The si mulation code is developed using the Kirkpatrick-Wiedmann-Statham equation and the formulae derived by Casnati and Gryzinski to describe generations o f continuous X-rays and characteristic X-rays, respectively. The results in dicate that a series of experimental X-ray spectra from W films of differen t thickness on Cu substrates have been reproduced by the present MC simulat ion with considerable success. A practical application for designing the op timum construction of a rotor-type X-ray source is also presented.
