Proposed additions to the SHADOW ray-tracing code for general-asymmetric perfect-crystal optics

PDF Version Also Available for Download.

Description

The dynamical theory of the diffraction of X-rays from perfect crystals is traditionally expressed in terms of Maxwell`s equations using a semi-classical theory originally due to Ewald and von Laue. Combining the work of Batterman and Cole, Caticha and Caticha-Ellis, and Zachariasen, a formalism is obtained that treats the general asymmetric, thick and thin crystal, Laue and Bragg cases within the second order dispersion surface approximation. The authors have implemented this formalism with thick Bragg crystal E-field boundary value conditions in several routines they have added to one of the Advanced Photon Source (APS) versions of the SHADOW ray-tracing code ... continued below

The authors have implemented this formalism with thick Bragg crystal E-field boundary value conditions in several routines they have added to one of the Advanced Photon Source (APS) versions of the SHADOW ray-tracing code in order to provide the ability to ray trace inclined double-crystal monochromators and high-resolution backscattering analyzers. These additions have been submitted to the University of Wisconsin Center for X-Ray Lithography for consideration for inclusion in the next version of SHADOW.
