A resonant detector for high-energy inelastic neutron scattering experiments

Results on the application of the resonant detector (RD) for epithermal neutron scattering in an unexplored kinematical region are presented. The RD is based on resonance radiative neutron capture for energy analysis of the scattered neutrons in an inverse geometry time of flight spectrometer. Application of the RD to detection of epithermal neutrons at very low scattering angles allows access to an unexplored scattering kinematical region, the High-energy Inelastic Neutron Scattering (HINS) region, of low wave vector (3 A(-1)<q<10 A(-1)) and high energy transfers (0.1 eV<omega<10 eV). Results of HINS measurements from polycrystalline ice are presented. (C) 2004 American Institute of Physics.
