Outline of Final Research Achievements

For comprehensive understanding of disruption phenomena observed in Tokamaks, the analysis codes for the thermal quench, the current quench and the generation of runaway electron are developed. The main results are given as follows: 5 dimensional relativistic Monte Carlo code ETC-Rel is extended to handle with heat load on the wall due to runaway electrons, taking account of generation mechanism of runaway electrons, loss mechanism by collision and radiation and so on. The model which determines the loop voltage during the generation of runaway electrons is implemented into the Fokker Planck code TASK/FP. As the result, the simulation which evaluates the generation rate of runaway electrons self-consistently is realized. It enables us to predict the amount of runaway electron generation in ITER plasma, quantitatively.
