The torsatron without toroidal field coils as a solution of the divertor problem

The torsatron without toroidal field coils is a configuration of the stellarator type which is obtained with a particularly simple set of conductors (ℓ helical windings and a vertical field). Here the case ℓ=3 is studied by numerical calculation. It is found that good magnetic surfaces exist. High values of rotational transform (ι/2π≃3) and shear (θ ≃ 0.5) can be obtained simultaneously with a relatively low mirror ratio along the field lines (Bmax/Bmin ≃ 1.2). The absence of separate toroidal field coils allows the design of an efficient divertor.

トロイド磁場コイルを有さないトルサトロンは、特に単純な導体セット(ℓ個のヘリカル巻線と垂直磁場)によって実現されるステラレーター型の配位である。ここでは、ℓ=3の場合を数値計算により検討した。良好な磁気面が存在することが見出された。高い回転変換(ι/2π≒3)とシア(θ≒0.5)を、磁力線に沿った比較的低いミラー比(Bmax/Bmin≒1.2)と同時に得ることができる。独立したトロイド磁場コイルが不要であることにより、効率的なダイバータの設計が可能となる。
