Thermal equilibria of detached plasmas and density limits

P.N. Guzdar, C.S. Liu, J.Q. Dong1988年被引用 5Nuclear FusionIF 3出版社

A theoretical investigation of the thermal equilibria of detached plasmas has been performed. The transport model used is that for the ηe modes. The model explains the scaling of the plasma radius, central electron temperature, impurity radiation, electron energy confinement time with plasma current and central density as observed on TFTR. Furthermore, assuming that the plasma disrupts when the safety factor reaches two at the edge of the detached plasma, a density limit ncr is obtained. For the impurity density nI independent of the plasma density, whereas for nI = fn(0), where f is the fraction of impurities, ncr ∝ BT/R.

非接触プラズマの熱平衡に関する理論的調査が行われた。使用された輸送モデルはηeモードに対するものである。このモデルは、TFTRで観測されたように、プラズマ半径、中心電子温度、不純物放射、電子エネルギー閉じ込め時間のプラズマ電流および中心密度に対するスケーリングを説明する。さらに、安全係数が非接触プラズマの端で2に達したときにプラズマがディスラプションを起こすと仮定すると、密度限界ncrが得られる。不純物密度nIがプラズマ密度に依存しない場合、 一方、nI = fn(0)の場合(ここでfは不純物の割合)、ncr ∝ BT/Rとなる。
