Results guide to CEPXS/ONELD: A one-dimensional coupled electron-photon discrete ordinates code package

Lorence Jr., L.J.; Morel, J.E.; Valdez, G.D.

CEPXS/ONELD is a discrete ordinates code package for one-dimensional coupled electron-photon transport over the energy range of 100 MeV to 1.0 keV. In this Results Guide, CEPXS/ONELD predictions are compared to the predictions of Monte Carlo codes and to experiment. These comparisons are made for a variety of quantities, including energy deposition, charge deposition and electron current spatial profiles as well as electron and photon spectra. Sensitivity studies are presented that show how the numerical approximations of CEPXS/ONELD can affect the accuracy of predictions. Guidelines for the efficient and accurate use of the code package are given. All examples involve one-dimensional planar geometry and non-adjoint transport. 35 refs.
