Abstract:
The extension of the atmospheric pressure air glows to centimeter and larger volumes has been demonstrated: in transverse direction through parallel operation of two single microhollow cathode sustained glow discharges, in longitudinal direction through increased voltage operation. Limits in discharge stability dependent on the discharge current have been explored. It was found that dc operation is limited to approximately 20 mA per microhollow cathode discharge. Pulsed operation allowed us to increase the current up to approximately 100 mA in the microsecond time regime before glow-to-arc transition occurs.
