A new white beam single crystal and powder diffraction facility at the SRS

Abstract

A new white beam single-crystal Laue diffraction (LD) and energy-dispersive powder diffraction (EDPD) facility has been constructed on station 9.7 of the SRS. This station receives radiation from a 5-T superconducting wiggler magnet with useful photon flux from 5 to 60 keV and a peak flux on the sample of 7×1011 photons/s/mm2 in a 0.1% bandwidth at 10 keV. The novel design of this facility allows rapid changeover between the two experiments without compromising either. Components have been built in a modular manner for ease of optimization for a particular set of data capture conditions.
