Electron losses from the magnetosphere.

A semi-empirical method for modelling the loss of electron fluxes in the earth's magnetosphere was developed. An equation for the integral-energy omnidirectional electron flux as a function of time and magnetic field strength was derived from pitch-angle diffusion theory. This flux equation was the basis for a computer data-fitting program written at the Air Force Weapons Laboratory (AFWL) to fit the AFWL Trapped Electron Daoa Base. The program utilised a least-squares fit and incorporated random variations of the characteristic exponential loss times about their initial values. Ad improved table of initial less times was compiled for use with the program. The derived flux model showed substantial agreement with the empirical data base. Representative plots of computed flux over raw data are shown for L-values of 2.3 and 2.4.
