Runaway-electron-dominated discharges in ORMAK

D.W. Swain, S.J. Zweben1980年被引用 9Nuclear FusionIF 3出版社

Near the end of the ORMAK tokamak operation, a series of experiments was performed in which the bulk of the toroidal current was carried by relativistic runaway electrons. New or improved measurements of RF and microwave emission, electron temperatures, and hard-X-ray flux were made. Of particular interest is the observation that the RF signal levels are remarkably low, less than a conventional (non-runaway) discharge. The data are compared with two runaway electron creation models and tend to agree better with a model in which runaways are created continuously throughout the discharge.

ORMAKトカマク運転の終盤において、トロイダル電流の大部分が相対論的逃走電子によって担われる一連の実験が実施された。RFおよびマイクロ波放射、電子温度、硬X線フラックスの新規または改良された測定が行われた。特に注目すべきは、RF信号レベルが通常の(非逃走)放電よりも著しく低いという観測結果である。得られたデータは、2つの逃走電子生成モデルと比較され、放電全体を通じて逃走電子が連続的に生成されるモデルとより良く一致する傾向を示した。
