Atmospheric Pressure Micro Inductively Coupled Plasma Source with Floating Electrode
ORAL
Abstract
Atmospheric pressure micro-ICP source is realized. Cu coil electrode and trench are prepared by milling glass epoxy substrate. U-shaped coil electrode is 9mm wide and 50mm long. Plasma ignition is promoted with the floating electrode placed inside the channel for the gas flow. Micro-ICP is generated at $\sim $35W of 100 MHz with He gas flow. In the spectra, O and OH peaks are observed in addition to He or Ar peaks, but metal (W) or C peaks are not observed. The device shows durability against $>$5h operation.
