Abstract

It is possible to use the D17 neutron reflectometer at the Institut Laue-Langevin as a direct geometry time-of-flight spectrometer. The kinematic constraints for the measurement of incoherent scattering and inelastic scattering from highly oriented samples are presented, along with an initial discussion of the energy resolution of the instrument. Inelastic scattering from water and polycarbonate are measured and contrasted with scattering from vanadium. The implications and possibilities for the future measurement of inelastic scattering are discussed.
