Beamline 33-BM-C: Multi-Purpose General Scattering

X-ray Science Division, APS
Materials Science, Physics, Chemistry

Description

This facility provides advanced x-ray scattering and diffraction techniques to a diverse scientific community. Station 33-BM-C is a multi-purpose scattering facility capable of high-resolution scattering with excellent energy resolution. This facility supports advanced materials research as well as condensed matter physics. Primary usage encompasses scattering and diffraction from thin-films, diffuse x-ray scattering, and general purpose diffraction.    The optical design of the beamline includes a vertically collimating x-ray mirror followed by a double crystal monochromator and a vertically focusing mirror. The double crystal monochromator uses sagittal focusing crystals for horizontal focusing. The mirrors are Pd coated to provide excellent harmonic rejection, and maintain excellent reflectivity below about 24 KeV. (For operations above 24 KeV, the mirrors are removed). The combination of optical elements is designed to allow maximum flexibility while preserving beam brilliance and simultaneously optimizing energy and momentum transfer resolution.
