Abstract

The experimental method of measuring neutron production double-differential cross sectionswas tested at incident proton energies of 0.8 and 1.5GeV with C and Pb targets. Neutronswere measured with liquid scintillators by the time-of-flight method. The use of very weaksecondary beam forced us to take a typical flight path length as short as 1m. Preliminaryexperimental consideration led to the results that the amount of back ground neutrons weremade low by the short flight path measurement, and a two-gate integration method was suitedfor the pulse shape discrimination between high energy neutrons and gamma-rays. The crosssections were obtained in the neutron energy range up to 100MeV with acceptable energyresolution. The experimental results obtained at the incident proton energy of 0.8GeV wereconsistent with the data taken with much longer flight paths. It was confirmed that the time-of-flight method with bare detectors at the short flight path was reliably applicable to thespallation neutron measurement.
