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