Outline of Final Research Achievements

In this research, we aim to develop a technology to melt ice and snow by chemical reactions caused by an atmospheric-pressure plasma instead of mechanical or thermal energy. The discharge characteristics at low temperature were measured. The discharge reactor, which can easily change the temperature from -15 ° C at a minimum and 100 ° C at a maximum was prepared. From the photograph of the discharge emission of light in a different temperature, we analyzed the emission intensity and the diameter of the streamer channel. The results shows that the diameter of the streamer is almost linearly changed under low temperature depending on the averaged reduced electric field.
