Zero-current high-beta stellarator equilibria with rotational transform profile control

Zero-current high-beta equilibria for a stellarator device are calculated using the averaging method. It is found that, by shaping the vertical field, the rotational transform can be controlled in an approximate way as beta is increased. At the same time, the Pfirsch-Schlüter currents are reduced – with no modification of the magnetic well. This permits access to the high-beta regime with more favourable rotational transform profiles. Results are presented for the Advanced Toroidal Facility (ATF) device.

ゼロ電流高ベータ平衡を、平均化法を用いてステラレーター装置について計算した。鉛直磁場を整形することにより、ベータが増加するにつれて回転変換を近似的に制御できることが見出された。同時に、ピルシュ・シュリューター電流は低減される——磁気井戸を変更することなく。これにより、より好ましい回転変換プロファイルを持つ高ベータ領域へのアクセスが可能となる。結果は、先進トロイダル装置(ATF)について提示される。
