The Energy Spectrum of Accelerated Electrons from Wave-Plasma Interactions in the Ionosphere
Abstract
A HAARP campaign was executed 1-15 April 2010. Dr. Bjorn Gustavsson attended from the United Kingdom with optical equipment from Sweden and the United Kingdom. Unfortunately, no useful data were obtained. It was therefore necessary to find the resources to repeat the campaign effort (see budget below). A HAARP campaign was executed 21 March-5 April 2011. Dr. Bjorn Gustavsson (3/21-4/5) and Prof. Mike Kosch (3/21-3/25) attended from the United Kingdom with optical equipment from Sweden and the United Kingdom. Very good optical data were obtained at multiple wavelengths (427.8, 557.7, 630.0, 7320.0, 777.4, and 844.6 nm). However, the emissions were highly structured in space and time. This fact, and the lack of electron temperature data at HAARP, made data analysis difficult. It became necessary to develop a quantitative model of the pump-wave self-absorption in the ionospheric D-region (publication 1), a quantitative model of electron heating in the ionospheric F-region (publication 2) taking into account D-region absorption, and an empirical model of electron temperature and optical emission intensity enhancements (publication 3) as a function of pump wave power. These tasks have been completed (see publications 1-3) using the EISCAT facility with its incoherent scatter radar, so progress on the originally specified task at HAARP can now be made.
