W16.1: A new fixed wavelength diffraction station at the SRS Daresbury

Abstract

Station W16.1 is a fixed wavelength (1.4 Å) x-ray diffraction station recently constructed and commissioned at the SRS. It has been designed specifically for time-resolved studies of noncrystalline and fibrous materials and optimized for low angle measurements. Wide angle diffraction will also be available with simultaneous small and wide angle scattering/diffraction a future facility. In order to perform dynamic (∼1 ms) low angle measurements on weakly scattering systems, the station design has had to incorporate several novel features so as to achieve the predicted 1×1013 photon/s at the specimen.
