Background, motivation, concept and scientific aims for building a dynamic ergodic divertor

K.H. Finken, G.H. Wolf1997年Fusion Engineering and DesignIF 1.7出版社

AbstractThe dynamic ergodic divertor is a new concept for distributing the power flux from the plasma to a large area target plate while keeping or even improving the particle removal capabilities of the toroidal pump limiter ALT-II. The transport in the ergodized boundary magnetic field shields the impurities from penetrating into the central plasma while the option of a radiative mantle should become even more efficient. To achieve the ergodization, a set of perturbation coils is oriented parallel to the field lines of a resonant layer (q=3 layer). A four phase perturbation current (up to 15 kA) is selected to impose the option of field rotation; the available frequencies are DC, 50 Hz and the band between 1 and 10 kHz. The low frequency option is chosen for smearing out the divertor strike point while the rotation high frequency option may give rise to a `temporal' ergodization in addition to the spatial one and may improve the plasma confinement and increase the disruption limit.

動的エルゴディックダイバータは、トロイダルポンプリミターALT-IIの粒子除去能力を維持またはさらに向上させながら、プラズマから大面積ターゲットプレートへのパワーフラックスを分散させるための新しい概念である。エルゴダイズされた境界磁場における輸送は、不純物が中心プラズマへ侵入するのを遮蔽し、一方で放射マントルのオプションはさらに効率的になるはずである。エルゴダイゼーションを達成するために、一組の摂動コイルが共鳴層(q=3層)の磁力線に平行に配向される。磁場回転のオプションを課すために、四相摂動電流(最大15 kA)が選択される。利用可能な周波数は、DC、50 Hz、および1~10 kHzの帯域である。低周波数オプションはダイバータ打撃点を平均化するために選択され、一方で回転高周波数オプションは、空間的エルゴダイゼーションに加えて「時間的」エルゴダイゼーションを生じさせ、プラズマ閉じ込めを改善し、ディスラプション限界を増大させる可能性がある。
