Outline of Final Research Achievements |
Development of accurate predictive model of disruption, especially halo current, is important since disruption leads to a huge damage for nuclear fusion reactor. In this study, we investigated the halo current prediction model by using a combination between experimental data and disruption simulation code, and obtained the following findings: (1) The decay of plasma current with a low electron temperature during the disruption is determined by the area-averaged value of electron temperature. (2) time change of electron temperature profile which is caused to the decay of plasma current is related to MHD instability just before disruption occurs. (3) Conductive structures are very important for a strong returning force to oncoming plasma when a vertical displacement event is occurred.
