A Facility for Studying Neutron Energy Spectra at Intermediate Energies

Abstract

Apparatus for measuring neutron energy spectra in the 50-200 MeV range is described. The apparatus, installed at the Indiana University Cyclotron Facility, consists of a beam swinger to change the angle of incidence of the beam on target, 100 m flight paths, large, subnanosecond neutron detectors, and a system for deriving phase stabilized timing signals.
