| Research Abstract |
An ion trap is a suitable device for the study of the effect of inter-particle correlation in a plasma, since the gas, liquid, and solid phase plasmas are able to be generated under well-controlled condition using the laser cooling method. Since the correlation effect is thought to appear as small modification of the spectrum shape, it is important to improve the accuracy of the diagnostics to find it. In this study, we developed a microscopic laser induced fluorescence (LIF) system for the diagnostics of a tiny one-component laser-cooled plasma. In addition, we improved the tuning range and stability of the laser systems in order to achieve wider range of ion temperature and better stability of the plasma. We performed the detailed study of the change of the spectrum shape, and found the change of Coulomb screening mechanism in the moderately-coupled plasma.
