Outline of Final Research Achievements

With an effect of pseudo micro gravity circumstances, an array of fine particles along the gravity direction was found in electric field emitting surface DBD of CO2 under high pressure condition up to supercritical fluid. Moreover, with a similar experiment, an array of fine magnetic fine particles was also found for a formation of functional plasma crystal under pseudo micro gravity circumstances. These achievements demonstarte the first great step to formation of isotropical three dimensional dust plasma and functional plasma crystal on the ground.
