Abstract
The gamma-ray background in the pulsed neutron beam at the Los Alamos Neutron Scattering Center was measured with an array of B-10-loaded li quid scintillators. With the method employed the gamma-ray contributio n in the neutron beam can be determined without knowledge of the energ y spectrum of the gamma-rays. The ratio of gamma-ray to neutron intens ities in the beam was determined during the time interval following th e beam burst that corresponds to neutron energies from E-n = 1 to 340 eV. The gamma-ray content in the beam ranges from 2% at 1 eV to 10% at 340 eV.
