逆磁場ピンチにおける核融合研究の現状と長期的展望

概要

The Reversed Field Pinch (RFP) has been believed to be dominated by anomalous transport due to strong magnetic fluctuations as with other low safety factor systems. However, for the last decade, RFP research has achieved significant progress in understanding its confinement physics. As a result, suppresion of the dynamo-induced fluctuations by controlling the current density profile has realized remarkable improvements in energy confinement time. Issues for near-term RFP research on the part of fusion programs includes active plasma control for confimenent improvement, stable operation for durations far exceeding the field penetration time of the conducting shell, heat and particle control, and possible optimization of the RFP configuration. Long term perspectives are also discussed.
