The Harwell 30 Mev electron linear accelerator was modified to provide electron bursts of 10 nsec duration at a repetition rate of 250 pps and peak current 0.2 amp. A neutron time-of-flight spectrometer was set up to cover the neutron energy range from 0.5 Mev up to approximates 15 Mev. The timing system incorporates a 1000 channel analyzer, each channel having a duration of 4.3 nsec. Using a 20 meter flight path, a typical overall energy resolution of 40 kev at 2 Mev is achieved. Measurements of the energy spectra of photoneutrons from the reaction S/sup 32/( gamma ,n)S/sup 31/ when irradiated with 20 Mev bremsstrahlung demonstrate the performance of the spectrometer. (auth)
