Characteristics of fusion reaction rate and neutron yield in deuterium plasma

Setsuo Niikura, Masayuki Nagami, Hiroshi Horiike1988年Fusion Engineering and DesignIF 1.7出版社

Characteristics of the fusion reaction rate and the fusion neutron yield have been investigated taking into account the effect of fast ions. The dependences of the fusion reactivity (〈σν〉B) and normalized fusion reaction rate (QB) on the fast ion energy and target plasma temperature are clarified. The following reactions are considered: (1)D0→D+(D(d,n)3He),(2)D0→D+(D(d,p)T),(3)D0→T+(T(d,n)4He),(4)Tf→D+(T(d,n)4He),(5)D0→H3e+(H3e(d,p)4He),(6)H3ef→D+(H3e(d,p)4He).The mutual relation of 〈σν〉B and QB for each reaction is also clarified. Furthermore, the fusion neutron yield (Fn) has been evaluated using a simple steady-state plasma model in which the radial profiles of the plasma temperature and density or the fast-ion velocity distribution are the same as those observed in recent experiments. The results of this model agree with those of the other calculational model. We have studied the following dependence for JT-60 plasma size: Fnvs.n¯e,Fnvs.τE,Fnvs.n¯e(using⁡Kaye−GoldstonorINTORscaling),Fnvs.nD/(nD+nH),Fnvs.EB,andFnvs.Ti/Te.

高速イオンの効果を考慮して、核融合反応率と核融合中性子収量の特性が調べられた。核融合反応度 (〈σν〉B) と規格化核融合反応率 (QB) の高速イオンエネルギーおよびターゲットプラズマ温度への依存性が明らかにされた。以下の反応が考慮される: (1)D0→D+(D(d,n)3He),(2)D0→D+(D(d,p)T),(3)D0→T+(T(d,n)4He),(4)Tf→D+(T(d,n)4He),(5)D0→H3e+(H3e(d,p)4He),(6)H3ef→D+(H3e(d,p)4He)。各反応についての〈σν〉BとQBの相互関係も明らかにされた。さらに、核融合中性子収量 (Fn) は、プラズマ温度と密度の径方向分布または高速イオンの速度分布が最近の実験で観測されたものと同じである単純な定常プラズマモデルを用いて評価された。このモデルの結果は、他の計算モデルの結果と一致する。我々は、JT-60プラズマサイズについて以下の依存性を研究した: Fn vs. n̄e, Fn vs. τE, Fn vs. n̄e (Kaye-GoldstonまたはINTORスケーリングを用いた), Fn vs. nD/(nD+nH), Fn vs. EB, および Fn vs. Ti/Te。
