Outline of Final Research Achievements

I designed and developed a new spectroscopic measurement system which enables to measure the high-resolution vibration-rotation emission spectra of the molecular species generated in the reactive region the atmospheric pressure plasma. The system consists of the Germanium Immersion Grating Mid-Infrared Cryogenic Spectrograph(GIGMICS) which have recently been succeeded in the development by us, and the new cryogenic reaction chamber. This enables us to measure the weak spectrum of the atmospheric pressure plasma with high sensitivity and high resolution.
