Characteristics of high-density tokamak ignition reactors

We determine the parameters of a tokamak reactor plasma that attains ignition in the same regime of collisionality, νeiA/ωbe, as present-day Ohmic-heated tokamak plasmas. The 'collisional' regime is attractive because the presently observed confinement scaling, nτ ∝ n2, can be employed, and fusion power densities can be very large (∼10 W/cm3). The use of Nb3Sn toroidal field coils and a plasma elongation ⪆ 1. 5 are necessary to attain the high plasma density (n ≈ 5 × 1014 to 1015 cm−3) required for ignition in this low-temperature collisional regime.

我々は、現在のオーミック加熱トカマクプラズマと同じ衝突性領域(νeiA/ωbe)において点火を達成するトカマク反応器のパラメータを決定する。「衝突性」領域は、現在観測されている閉じ込めスケーリング則(nτ ∝ n2)を適用でき、核融合出力密度を非常に大きくできる(∼10 W/cm3)ため魅力的である。この低温衝突性領域で点火に必要な高密度(n ≈ 5 × 1014〜1015 cm−3)を達成するには、Nb3Snトロイダル磁場コイルとプラズマ伸長度(⪆ 1.5)の使用が必要である。
