A D-3He fusion reactor based on a dipole magnetic field

A. Hasegawa, Liu Chen, M.E. Mauel1990年被引用 85Nuclear FusionIF 3出版社

An innovative fusion reactor suitable for D-3He fuel is proposed; it is based on a dipole magnetic field produced by a levitated superconducting coil. The equilibrium plasma, whose phase space density satisfies ∂f̑0(μ,J,ψ)/∂ψ = 0, where ψ is the flux function, has a steep enough pressure profile for an efficient fusion reaction yet is stable to low frequency instabilities for local beta exceeding unity. At the outer wall, the plasma is stabilized by line tying or localized magnetic cusps which can be used for direct conversion. The fusion product confinement time can be controlled for ash removal by breaking the axisymmetry of the dipole magnetic field. A conceptual 70 MW reactor design is presented.

D-3He燃料に適した革新的な核融合炉が提案されている。これは、浮遊超伝導コイルによって生成される双極子磁場に基づいている。位相空間密度が∂f̑0(μ,J,ψ)/∂ψ = 0を満たす平衡プラズマ(ここでψは磁束関数)は、効率的な核融合反応に十分な急峻な圧力分布を有しながら、局所ベータ値が1を超える場合でも低周波不安定性に対して安定である。外壁では、プラズマはラインタイイングまたは局所磁気カスプによって安定化され、これらは直接変換に利用できる。核融合生成物の閉じ込め時間は、双極子磁場の軸対称性を破ることによって、灰除去のために制御可能である。概念設計として70MWの炉が提示されている。
