Spectroscopic Characterization of Microplasmas
Abstract
In this study, a new design for a unit discharge cell has been developed. It has a floating electrode in the well of the top electrode above the bottom electrode, in which the bright spot can be spatially fixed irrespective of the applied voltage phases. As an evidence of a new function driven from integrated structure, a frequency-dependent deformation phenomenon of mm-wave transmittance through a perforated metal-plate filled with microplasmas was observed. Also investigated discharge plasmas generated in artificial media: liquids with injected bubbles or atmospheric gases with mists. As a trial, a fabric-type electrode assembly dipped in aqueous solution of electrolyte was used and the discharge phenomenon in bubbles generated by electrolysis using optical emission spectroscopy was studied. The plasma emission spectrum in the discharge in bubbled water with a point-to-plane electrode configuration was observed and widely broadened line spectra of hydrogen atoms were measured. A study on the discharge in air with liquid mists has been tested as well with the developed mesh-electrode configuration with preliminary results.
