The evaluation of mode purity for ECCD using single deep grooved polarizer

M Saigusa, Y Kikuchi, N Takei, S Kanazawa, T Imai2001年Fusion Engineering and DesignIF 1.7出版社

AbstractA new type single mirror polarizing system is proposed for Electron cyclotron current drive (ECCD) in toroidal plasma. A single deep grooved mirror (DGM) can generate suitable elliptical polarizations for both of ordinary mode (O-mode) and extraordinary mode (X-mode) in oblique launch with a slanted magnetic field line. Estimated mode purity of O and X modes on the plasma surface is higher than 90% for almost all ECCD experimental condition.

トロイダルプラズマにおける電子サイクロトロン電流駆動(ECCD)のために、新型の単一ミラー偏波システムが提案されている。単一の深溝ミラー(DGM)は、斜め入射かつ傾斜した磁力線の条件下で、常波(Oモード)と異常波(Xモード)の両方に対して適切な楕円偏波を生成することができる。プラズマ表面におけるOモードおよびXモードの推定モード純度は、ほぼすべてのECCD実験条件において90%を超える。
