Outline Activities
Major activities are the experimental research of plasma turbulence.
Now I am taking charge in the conduction of the experiments in a linear cylindrical device, PANTA, development of analyzing methods of turbulence data
in Itoh research center for plasma turbulence and advance fusion research center of RIAM.
Now I am doing the design of the magnetically plasma confinement device of torus shape for plasma turbulence studies.

Current and Past Project
  • To control and predict the properties of the magnetically confined plasmas the worldwide researches have been vitally carried out toward realizing a burning plasma in International Tokamak Experimental Reactor (ITER). According to the recent achievement, the new concept is being established that the mesoscale fluctuating structure such as zonal flows and streamers coexist with microscale fluctuations, to regulate the turbulent transport. The new concept makes it enable to explain the changes in structure and transport occurring in much faster time scale than diffusive one. It is necessary to manage the dynamics changes in transport for control the burning plasma state, thus, the understanding of dynamics transport response should be mandatory. The purposes of this projects are i) to complete the paradigm shift from linear, local, deterministic view to nonlinear, non-local, probabilistic one, ii) to develop and advance the physics of turbulent plasma to accomplish the mode dynamics and nonlocal transport phenomena, and iv) to clarify the dynamic transport phenomena in the magnetically confined plasmas for provide a concrete base to control the burning plasma in ITER.
