    • Abstract

       

      A high resolution neutron spectrometer making use of a ΔT-window filter for the analyser and time-of-flight technique for analysing incident neutron energy has been designed. The spectrometer will provide a continuously variable energy resolution ΔE from 40–50µeV at ∼ 5230µeV. The range of energy transfer allowed is −1450µeV to +2950µeV and the range of wavevector transferQ allowed is 0·82–3·06 Å−1. Depending on the resolution used, the counting rates are expected to vary from 28–60 × 103 counts/hr if one assumes 10% isotropic elastic scattering from the sample.
