Two-Dimensional Transport Equation Calculations of Dose Profiles Due to Electron Beam Irradiation

Abstract
The Spencer-Lewis equation for kilovolt electron transport in two dimensions was solved using a discrete ordinates, diamond difference method. Calculations of dose profiles in 2-D were made for 200 keV electrons normally and isotropically incident on aluminum and are compared with ACCEPT Monte Carlo calculations. Isodose contour plots are also presented for 200 keV electrons making angles of 0 and 45 degrees with the normal. Running times compare very favorably with Monte Carlo.
