Ray-tracing of X-ray focusing capillaries

We report the use of multi-bounce ray tracing to model single capillaries of various profiles coupled to an Advanced Photon Source insertion-device beamline containing an X-ray monochromator and a toroidal or ellipsoidal focussing mirror. Examples are given for parabolic as well as linear profiles placed at the focussed output of the insertion device beamline for the Pacific Northwest Consortium Collaborative Access Team at the Advanced Photon Source. The implementation of single and multiple capillary simulation is discussed.
