Test facility for Atmospheric Pressure Plasmas
Abstract
In order to compare the various proposed methods of plasma generation in high pressure gases, particularly air, a test facility for atmospheric pressure plasmas has been established. The facility is located in the Applied Research Center of Old Dominion University (ODU). in Newport News. VA. The diagnostic instrumentation at the facility allows us to determine the electrical parameters of high pressure glow discharges, the temporal development of instabilities, the electron density, and the temperature at high spatial (micrometer) and temporal (ns) resolution. Diagnostic techniques developed under this grant are gas temperature measurements in air, based on the emission spectroscopy (rotational spectrum of the second positive system of nitrogen) and electron density measurements using a CO2 interferometer. In addition a 105 GHz microwave interferometer has been acquired and is available for measurements where a spatial resolution of only mm is required.
