Experimental Conditions for Observation of ThermodynamicInstability and Critical Point of Fine Particle (Dusty) Plasmas

東辻 浩夫 Graduate School of Natural Science and Technology, Okayama University
When the Coulomb coupling between fine particles becomes sufficiently strong in fine particle plasmas, the isothermal compressibility of the whole system diverges and we have a phase separation and an associated critical point. Experimental conditions of fine particle plasmas, densities and temperatures of components and the fine particle size, are obtained corresponding to characteristic parameters around the critical point and the dependency on ion species and other factors is discussed.
