Abstract
The Diamond Light Source beamline I12 (JEEP) is installing a monochromator for high-energy (50-150 keV) X-rays. It consists of two highly asymmetrically cut silicon crystals diffracting in the Laue case. These crystals will be bent to increase the bandpass to several hundred eV. It is necessary to estimate the tolerances for the angular alignment and the bending radii, and to account for gravitational and thermal distortions. A simple ray-tracing model has been developed for use with finite-element analyses. For simple cases, this model is backed by more precise wave-optical calculations.
