The Stabilization of an Atmosphere of Plasma Based Carbon Dioxide at Atmospheric Pressure
Zusammenfassung
Some reasons are discussed for the
stabilization of a glow discharge at atmospheric
pressure which was attained by controlling the
following three conditions: the use of a highfrequency source, the use of gas for dilution and the
insertion of a dielectric plate between electrodes.
The three conditions interact: the dielectric plate in
a plasma forms the pulsed discharge from a lowfrequency source, the fast duration of pulse current
prevents a transition to an arc style discharge and
a large volume of met stable atomic carbon dioxide
aids ionization or dissociation near the electrode
plate and in the flowing gas. The measurements of
discharge-maintaining voltage at several hundred
volts provide evidence that this is really glow
plasma at atmospheric pressure. The changes of
the emission intensities of metastable carbon
dioxide prove indirectly that some dissociation
occurs as a result of the action.
