Computing X-Ray Effects in Optics

摘要

In this paper, we discuss the physical phenomena that are important in understanding the behavior of optics exposed to X-ray fluences, and four computer programs that are commonly used to perform such calculations. We describe several model problems and spectra that we used to exercise the four computer codes. Finally, we close with a number of conclusions and recommendations for those who wish to use one or more of the codes to predict the response of optics to X-ray fluences. In particular, we find that multidimensional geometry issues must be carefully addressed and special care must be taken to insure that even the one dimensional calculations have converged. 3 refs., 11 figs.
