Paper Abstract

The re-emitted spectra and re-emitted power of hard x rays traversing solid material have been formulated analytically. The re-emitted x rays are due to the interaction of the incident x rays with the material through Compton scattering, Rayleigh scattering, and inner-shell vacancy radiative decay. Based on the formula, the re-emitted power of Compton and Rayleigh scatterings are calculated for the x rays from a SPring-8 Multi-Pole-Wiggler (MPW) traversing a graphite filter, a Be window, and an Al or a Cu filter. The percentage of the re-emitted power from an Si crystal due to Compton and Rayleigh scatterings as a function of the incident angle is also discussed.
