| Outline of Final Research Achievements |
AC trap of charged particles (few tens of thousands, few tens of micron in diameter) is developed to investigate collective phenomena, structure and fluctuation of particles, which are related to the phenomena predicted to be occurred in a crust of neutron star and, solid and liquid plasmas, and physics of large dimensional chaos. Main results are; (1)phonon mode in one component strongly coupled plasma was obtained. (2)Separation of particle structure to ordered and fluctuation ( melted) regions was observed in AC frequency and voltage phase space. Power spectrum of long time density fluctuation (1/f) was observed. (3) Large deviation statistic of particle velocities are observed.
