Comparison of Onetran Calculations of Electron Beam Dose Profiles with Monte Carlo and Experiment

Electron beam dose profiles have been calculated using a multigrouip, discrete ordinates solution of the Spencer-Lewis electron transport equation. This was accomplished by introducing electron transport crosssections into the ONETRAN code in a simple manner. Our purpose is to "benchmark" this electron transport model and to demonstrate its accuracy and capabilities over the energy range from 30 keV to 20 MeV. Many of our results are compared with the extensive measurements and TIGER Monte Carlo data published by Lockwood et al. In general the ONETRAN results are smoother, agree with TIGER within the statistical error of the Monte Carlo histograms and require about one tenth the running time of Monte Carlo.
