| Research Abstract |
In this study, employing microwave resonator probe available for electron density monitoring, we have investigated on application of the probe for atmospheric pressure plasma as well as extension of the probe function. In high-pressure plasma, resonance width of the observed probe spectra expands in proportional to electron density which suggests this method will be usable for electron density measurements. Accuracy of the measurement will be improved by considering resonance width observed without plasma. Further, we showed conditions for precise measurements in repetitive pulse discharge plasmas and possibility of simultaneous measurements of electron density and reactive species by installing optical fiber to the probe head on the basis of spectroscopic technique.
