Outline of Final Research Achievements |
The world-largest merging device MAST (Culham Science Centre, UK), and UTST (Univ. Tokyo) which has all the magnetic coils out of the vacuum vessel, are spherical tokamak merging devices in conditions close to the nuclear fusion reactor. In these devices, electron and ion heating during spherical tokamak merging startup was observed. At around the merging X-point, the electrons and ions were heated by the electric field induced by the reconnection, depending on the amplitude of the guide field. The ions were heated at the reconnection outflow region, and the heat was soon migrated to the electrons. From these observations, the heating effect of the merging startup was verified.
