EXCEDE Energy Deposition. Theory and Experiment Compared.

Abstract

This report describes work performed to determine the adequacy of code calculations (based on single particle deposition in ambient air) to describe the energy deposition rate surrounding electron beams at E-region altitudes in the atmosphere. Comparisons are made between model predictions and camera data from the PRECEDE II and EXCEDE:SPECTRAL experiments. Large discrepancies are found to exist between theory and experiment, at least for the EXCEDE:SPECTRAL event, in the region near the electron accelerator. The discrepancies are tentatively attributed to a beam plasma discharge effect that is not described by the standard theory. Recommendations are made for work to help clarify the phenomenon.
