Monte Carlo Modeling for Electron Microscopy and Microanalysis - 9

This book describes how Monte Carlo modeling methods can be applied to Electron Microscopy and Microanalysis. Computer programs for two basic types of Monte carlo simulation are developed from physical models of the electron scattering process; a Single Scattering program capable of high accuracy but requiring long computation times, and a Plural Scattering program which is less accurate but much more rapid. The programs are optimised for use on personal computers and provide a realtime graphical display of the interaction. These programs are then used as the starting point for the development of programs aimed at studying particular effects in the electron microscope including backscattering, secondary electron production, EBIC and cathodo- luminescence imaging, and X- raymicroanalysis. The computer code is given in a fully annotated format so that it may be readily be modified for use in specific problems. Many examples of the applications of these methods are provided, together with a complete bibliography.
