Neutron ray-tracing simulations for the upgrade of the OSIRIS spectrometer

ISISProject description
OSIRIS is a cold-neutron high-flux near-backscattering neutron spectrometer combined with a long-wavelength diffractometer, located at the ISIS Neutron and Muon Source. In this project we designed a new silicon analyzer and detector system for OSIRIS, with the use of neutron ray-tracing simulations as well as analytical calculations, which will improve the resolution and increase the dynamic range of the instrument. We further designed a new elliptic super-mirror neutron guide for OSIRIS that will significantly increase the flux and focus of the neutron beam on sample position, which will allow the routine measurement of smaller samples. These developments will facilitate challenging studies of novel materials and ensure that OSIRIS remains a highly competitive instrument.
