Abstract : A computer program, called the Injection Code, has been developed by the Air Force Weapons Laboratory for the purpose of predicting the intensity, extent, and duration of the trapped electron population resulting from a high-altitude nuclear detonation. A debris rise model has been formulated in which the debris is treated as a diamagnetic sphere. Omnidirectional flux is computed as a function of B, L, and longitude for early times and as a function of B, L for late times. Flux calculations are commonly run for L equal to or less than 3.0, using a beta fission spectrum, 0.5 equal to or less than Energy equal to or less than 6.5 Mev. Calculations are made for weapon detonations on geomagnetic field lines with equatorial altitudes greater than 100 kilometers and less than 10,000 kilometers. Natural environment contributions are not considered. A knowledge of high-altitude weapon phenomenology and characteristics are required to formulate the semi-empirical input parameters. (Author)
