LANSCE (Manuel Lujan, Jr. Neutron Scattering Center) target system performance
Description:
We measured neutron beam fluxes at LANSCE using gold foil activation techniques. We did an extensive computer simulation of the as-built LANSCE Target/Moderator/Reflector/Shield geometry. We used this mockup in a Monte Carlo calculation to predict LANSCE neutronic performance for comparison with measured results. For neutron beam fluxes at 1 eV, the ratio of measured data to calculated varies from /approx/0.6-0.9. The computed 1 eV neutron leakage at the moderator surface is 3.9 /times/ 10/sup …
