Tandem mirror reactor with octopole and wall stabilization

R.S. Devoto, W.L. Barr1987年被引用 1Nuclear FusionIF 3出版社

A tandem mirror reactor configuration with wall stabilization of the central cell and octopole stabilization of the end cell has been studied. The critical beta for wall stabilization of the central cell is reduced by the use of rippled magnetic fields. Consideration of erosion and heating of the first wall by alpha particles suggests that wall-to-plasma radii ratios of 1.15 are practical. Wall stabilization of the central cell reduces the required mantle beta in the end cell and improves the reactor potential of the octopole stabilized configuration. The properties of the operation of a typical small (overall length 85 m) reactor with 1250 MW of fusion power, a wall load of 4.4 MW·m−2 and a Q of 27 have been computed.

中央セルの壁安定化と端セルのオクタポール安定化を備えたタンデムミラー炉構成が研究された。中央セルの壁安定化の臨界ベータは、リップル磁場の使用により低減される。アルファ粒子による第一壁の侵食と加熱の考察は、壁対プラズマ半径比1.15が実用的であることを示唆している。中央セルの壁安定化は、端セルに必要なマントルベータを低減し、オクタポール安定化構成の炉としての可能性を改善する。典型的な小型(全長85 m)炉で、核融合出力1250 MW、壁負荷4.4 MW·m−2、Q=27の運転特性が計算された。
