Schematic of the system used at the BMIT bend-magnet beamline. (a) Plan view of the double-crystal monochromator (DCM), contrast material and detector. (b) Elevation view of the non-contrast or beam side; (c) elevation view with contrast material whose K-edge is at the vertical middle beam prepared by the DCM. Example plots at the right show the profile for the unfiltered beam (b) and contrast filtered beam (c). |
