OSIRIS can be used as either a high-resolution, long-wavelength diffractometer or for high-resolution quasi/ inelastic neutron scattering spectroscopy. For the purpose of description, OSIRIS may be considered as consisting of two coupled spectrometer components.
With regard to spectroscopy, it is a high-flux (owing to the super-mirror guides) time-of-flight inverted geometry instrument such that neutrons scattered by the sample are energy analysed by means of Bragg scattering from a large-area pyrolytic graphite crystal-analyser array. The analyser is associated with 42-element 3He detectors.
OSIRIS DASHBOARD (Monitor what is happening on OSIRIS)
With regard to diffraction, OSIRIS has a diffraction detector bank consisting of 962 ZnS tubes oriented at 2θ ∼ 170°. OSIRIS offers a d-range between 0.8Å and ∼ 20Å at high resolution and high counting rates.
NEW! A cooled and mechanically retractable Be filter has been installed and commissioned on the low-energy OSIRIS spectrometer at ISIS. See more details here.
