An associated particle 14-MeV neutron time of flight spectrometer for use with small accelerators

Abstract

The 14-MeV neutron time of flight spectrometer used with a 150-keV SAMES type J accelerator at the University of Aston is described. The use of the associated particle technique to provide a zero time signal is shown to produce count rates near to that produced by klystron bunching techniques and angular resolutions at least equal to those achieved on larger accelerators. The way in which the spectrometer is used to measure the differential cross-sections for elastic and inelastic scattering of 14-MeV neutrons for 14N is described.
