Infrared Program Supports EXCEDE and Related Topics

Abstract

Further work, related to EXCEDE experiments, and to LWIR emission processes, is described. Efforts to account for the enhanced optical emission observed in the EXCEDE:SPECTRAL experiment on the basis of excitation by hot plasma electrons, using the independent particle deposition model, failed. The data appear consistent with a beam-plasma discharge mechanism. Analysis of ground-based photographic data imply that the region of enhancement extends for several hundred meters along the earth's magnetic field. Study of plasma radiation from electron-beam irradiated air leads to the conclusions that EXCEDE is not the optimum tool for verifying our IR models for bound-bound recombination radiation.
