Plasma is the fourth fundamental state (phase) of matter following solid, liquid and gas. Familiar plasmas are lightning, the Northern Lights and the sun etc.. In this laboratory, we conduct a wide range of study from the basic studies, which are ""Simulation experiment of space plasma"" and "Measuring plasma properties and analysis of numerical simulation to realize power generation by nuclear fusion", to the application studies, which are "Magnetohydrodynamics (MHD) power generator and thruster" and "Metal surface treatment and treatment of marine microorganisms by an atmospheric pressure plasma". We handle a wide variety plasma and that is this laboratory's feature.
