Description

A new numerical solution to the two-stream equations for electron transport and thermalization is presented and discussed. The numerical code is verified by comparing computed results with the analytic results of Stamnes (1981) and with the Nagy-Banks code (Nagy and Banks, 1970). Further verification is provided by carefully testing for energy conservation. The computational speed depends primarily on the number of grid points in altitude utilized. It is demonstrated that useful results can be obtained with as little as 20-40 altitude grid points. The present numerical code represents an extension of the Nagy-Banks code to high electron energies appropriate for auroral applications. This extension is accomplished by using the energy degradation method of Swartz (1977) and the backscatter ration of Stamnes (1981).
