Abstract:Spatial distributions of energy deposition rates in EXCEDE Spectral's 3 keV, 7 A electron beam injection at E region altitudes derived from onboard photographic images of the air fluorescence are presented and compared with a time‐dependent computational model of the collective beam‐plasma interaction. The volume excitation rates decrease with a scale length of order 1 m near the rocket, are ∼2 orders of magnitude greater than predicted from single particle transport calculations, and at fixed distances from t… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
