There are two neutron sources at Los Alamos National Laboratory (LANL) that are used for nuclear data measurements. Both use part of the 800-MeV proton beam from the Los Alamos Meson Physics Facility to produce neutrons by spallation. The Los Alamos Neutron Scattering Center (LANSCE) provides useful neutron intensities from subthermal to {approximately}100 keV using a target-moderator source. The Weapons Neutron Research (WNR) facility has a bare target that gives a neutron spectrum with energies from 100 keV to 800 MeV. Each of these is a white source making it possible to cover a broad energy range in a single measurement using neutron energy determination by time of flight. The performance of these two as complementary pulsed neutron sources is much superior to that of electron linacs traditionally used for measuring nuclear data in the thermal/epithermal region and the range above a few mega-electron volts. The scope of work at LANL includes studies related to space exploration, medical research, radioactive waste disposal, and innovative energy production concepts as well as information for fission and fusion programs. Nuclear-data-related work at the WNR facility includes measurements of medium-energy proton-induced cross sections, neutron-induced gamma-ray and charged-particle production; fission studies; and neutron total cross-section experiments.
