Physics of plasma control towards steady-state operation of ITER
نویسندگان
چکیده
ITER is a fusion experimental reactor to show scientific and technological feasibility of fusion energy. It is designed to produce fusion power of 500MW for 300-500 seconds with fusion energy gain Q at least 10 (Q ≥10) [1], [2]. ITER should show scientific and technological feasibility of fusion energy as one step to DEMO, which produces electricity by fusion energy. Although design of DEMO will depend on the outcome of ITER, steady-state tokamak reactor [3] utilizing the bootstrap current [4] is an attractive candidate of DEMO. ITER research has to be undertaken by considering the application to DEMO in mind. Plasma control in ITER is one of essential elements to fulfill ITER mission, which is the main theme of this 4th ITER summer school. In this introductory talk, I will introduce fundamentals of plasma control in tokamak and key physics to establish steady-state operation of ITER.
