Title: The Design of the Sagittal Focusing Monochromator for XAFS Measurement at NSRL

Abstract

The main project of XAFS beamline upgrading at NSRL is to replace the double crystal monochromator with the sagittal-focusing one, of which the diffraction and the focus are compatible. It will increase the photon intensity more than 5 times on the sample with M=1:4.88 geometry and 3 x 0.1 mrad2 acceptance divergence (H x V) without other changes at the primary beamline configuration. This paper introduces concept design of the sagittal-focusing monochromator including optical design, parameters calculation, heat load analysis, mechanical analysis of the flexural hinge-based bender and the mechanism of dynamically energy scanning.
