Comparison of theory with electron cyclotron current drive experiments on WT-2

A simple analytical model of the non-Maxwellian electron velocity distribution, whose parameters are constrained by the observed plasma current and soft X-ray emission spectrum, is used in conjunction with a fully three-dimensional ray tracing code to calculate the absorption of radiation in the electron cyclotron range of frequencies by WT-2 discharges. This gives a quantitative, theoretical description of the way in which a drifting population of energetic electrons appears to dominate WT-2 current drive experiments. Calculation of the proportion of source power absorbed by the plasma helps to determine the efficiency factor of the current drive mechanism in this context. The strong dependence of current drive on the extraordinary mode launch direction is given theoretical support.

非マクスウェル電子速度分布の簡潔な解析モデル(そのパラメータはプラズマ電流と軟X線放射スペクトルの観測値によって拘束される)を、完全な3次元光線追跡コードと組み合わせて用い、WT-2放電における電子サイクロトロン周波数帯の放射の吸収を計算する。これにより、ドリフトする高エネルギー電子集団がWT-2電流駆動実験を支配する様子を定量的に記述する理論的枠組みが得られる。プラズマによる入射電力の吸収割合を計算することで、この状況における電流駆動機構の効率因子を決定できる。異常波の入射方向に対する電流駆動の強い依存性は、理論的に裏付けられる。
