On the extrapolation to ITER of discharges in present tokamaks

An expression for the extrapolated fusion gain G = Pfusion/5Pheat (Pfusion being the total fusion power and Pheat the total heating power) of ITER in terms of the confinement improvement factor (H) and the normalized beta (βN) is derived in this paper. It is shown that an increase in normalized beta can be expected to have a negative or neutral influence on G depending on the chosen confinement scaling law. Figures of merit like should be used with care, since large values of this quantity do not guarantee high values of G, and might not be attainable with the heating power installed on ITER.

外挿された核融合利得G = Pfusion/5Pheat(ここでPfusionは全核融合出力、Pheatは全加熱出力)のITERにおける表現が、閉じ込め改善係数(H)と規格化ベータ(βN)の関数として本論文で導出される。規格化ベータの増加は、選択された閉じ込めスケーリング則に依存して、Gに対して正または負の影響を与えることが示される。このような量の大きい値がGの高い値を保証するものではなく、またITERに設置された加熱出力では達成できない可能性があるため、性能指数は注意して使用されるべきである。
