Abstract
Neutron time-of-flight measuring system is described. A 3 MV Van de Graaff accelerator is equipped with a beam pulsing system which can produce pulses as narrow as 3 ns FWHM with residual beam less than 10" times the peak current. An elevated target station reduces scattered neutron and gamma-ray background by more than a factor of four compared with a conventional near-ground location. Neutrons are detected by an NE213 scintillator, for which construction and calibration details are given. A computer-based control and data acquisition system allows automatic measurements of angular distributions.
