Prediction of Time-Dependent Neutron Fluxes Encountered in Pulsed-Neutron Uranium Logging Experiments

One-dimensional time-dependent neutron transport calculations have been performed to predict the signals that would be observed in pulsed-neutron uranium logging experiments. Although the actual experimental geometry had to be idealized somewhat to conform to the one-dimensional nature of the calculations, the results clearly show the essential features of the logging signal. These calculations are economical enough that parameter studies are feasible.
