| Outline of Final Research Achievements |
"Steady state operation(SSO)" is an indispensable prerequisite for fusion reactor. The present study is aimed at to clarify the fueled particle circulation in three systems, core, boundary, and first wall. Elementary processes, the system interaction, a circulation model, control of the particle circulation, long sustainment and influence of fueling on the intrinsic plasma flow are subjects to build the foundation for SSO. Thus "Physics and macro control of particle circulation in a multi hierarchical complex-open system" is introduced. The elucidation of the circulation in each system and the mutual interference leads to the key macro control of the whole system. The following results has been achieved,1)70 kA non-inductive plasma current by radio-frequency waves, 2)application of the response function method to evaluate particle circulation, 3)intrinsic flow reversal in the core plasma by the fueling, and 4) steady tokamak operation for 6 hours by using the hot wall at 200 ℃.
