ECE imaging on TEXT-U

G Cima, B Deng, C.W Dormer, W.R Geck, D Brower1997年Fusion Engineering and DesignIF 1.7出版社

AbstractThe principles of plasma electron cyclotron (EC) radiometry are reviewed. The aim is to lay the groundwork for discussion of new high performance electron cyclotron emission (ECE) detectors. One example is that of heterodyne arrays. Preliminary results are presented of data obtained with a novel ECE imaging system on TEXT-U based on such an array. A variety of preliminary experiments have already been performed with this system where the ultimate space and time resolutions of ECE are attained. As examples we cite average electron temperature profile measurements with 1 cm resolution, high frequency fluctuations and their vertical chord correlation, magnetohydro-dynamic mode reconstruction and magnetic island detection.

プラズマ電子サイクロトロン放射(ECE)放射測定の原理を概説する。その目的は、新しい高性能電子サイクロトロン放射(ECE)検出器の議論の基礎を築くことである。一例として、ヘテロダインアレイが挙げられる。そのようなアレイに基づくTEXT-U上の新規ECEイメージングシステムを用いて得られたデータの予備的結果を示す。このシステムを用いて、ECEの究極的な空間分解能および時間分解能が達成される多様な予備実験がすでに実施されている。例として、1cm分解能での平均電子温度プロファイル測定、高周波変動とその鉛直方向相関、磁気流体力学モード再構成、および磁気島検出を挙げる。
