Outline of Final Research Achievements

The objective of this study is to extend the MHD equilibrium model of the current hole plasma and study validity of the model by comparing the calculation results with the experimental observation. The simulation of time evolution of the current profile in JT-60 current hole plasma indicates existence of anomalous diffusion of electrons or electron current in the current hole. A module for calculating an axisymmetric equilibrium considering current by fast ions with orbits shifted from the flux surface has been developed, in order to analyze the neutral-beam-driven current in the current hole plasma. The high-Z impurity transport model has been improved and the calculated accumulation of tungsten ions was close to the experimental observation in JT-60.
