Complex Plasma Systems Research Section

概要

Magnetic nuclear fusion energy has some attrac- tive features as a future option for the base-load elec- trical power source: (1) inherent safety features, (2) no long-life nuclear waste emission, (3) no greenhouse gas emission during the energy production, (4) huge energy density stored in the fuel source(~90 MWh/g for D-T fuel), (5) abundant source availability spread- ing all over the Earth, and (6) high nuclear prolifera- tion resistance, in terms of both resources and weap- ons technologies.

Among various issues to be overcome in physics and engineering fields, we have focused on the problems related to the plasma transport and magneto-hydrody- namics. Specifically, determination of a magnetic con- figuration that can efficiently confine high-density plasma at high temperature with a sufficiently long confinement time and developing diagnostics and con- trol schemes for the high-temperature plasmas in such magnetic fields are regarded as crucial. In these re- spects, our research section investigates about heating and fueling, confinement and diffusion mechanisms and their diagnostics in a magnetic plasma confine- ment device, named Heliotron J.

Results in FY2020 featured in this report are about the comparison between the experiments and the- ory/simulation in turbulent and MHD phenomena.
