The safety factor profile in the RFP plasma core from soft x-ray tomography

G Spizzo, P Franz, L Marrelli, P Martin2001年Plasma Physics and Controlled FusionIF 2.2出版社

We report experimental results on the identification of rational surfaces in the Reversed Field Pinch (RFP) plasma core. The position of rational surfaces has been obtained from tomographic measurements of the m = 1structure which develops during Quasi-Single Helicity (QSH) states. These results allow the estimate of the safety factor profile, whichis measured for the first time in a RFP with plasma current ≈1 MA.

我々は、逆転磁場ピンチ(RFP)プラズマのコアにおける有理面の同定に関する実験結果を報告する。有理面の位置は、準単一ヘリシティ(QSH)状態の間に発達するm = 1構造のトモグラフィー計測から得られた。これらの結果により、プラズマ電流≈1 MAのRFPにおいて初めて測定された安全係数プロファイルの推定が可能となる。
