Outline of Final Research Achievements

We surveyed the condition for high beta plasma production by an electrode biasing in the spatial axis stellarator (Tohoku University Heliac). We can obtained transition conditions for the improved confinement mode in helical systems and we can successfully summarize the dependence between configuration of magnetic fields and the poloidal viscosity at a local maximum in Tohoku University Heliac and domestic helical systems. And we also proposed the evaluation method for the confinement performance of high energy particles (alpha particle) in advanced small helical devices and surveyed the condition for high energy particle injection by the hydrogen storage electrode. The experimental result suggests that hydrogen ions were accelerated by the hydrogen storage electrode biasing.
