Electron temperature in field reversed configurations and theta pinches with closed magnetic field lines

A.A. Newton1986年被引用 9Nuclear FusionIF 3出版社

Field-reversed configurations (FRC) and theta pinches with trapped reversed bias field are essentially the same magnetic confinement systems using closed magnetic field lines inside an open-ended magnetic flux tube. A simple model of joule heating and parallel electron thermal conduction along the open flux lines to an external heat sink gives the electron temperature as Te(eV) ≅ 0.05 B2/3(G) L1/3(cm), where B is the magnetic field and L is the coil length. This model appears to agree with measurements from present FRC experiments and past theta-pinch experiments which cover a range of 40–900 eV. The energy balance in the model is dominated by (a) parallel electron thermal conduction along the open field lines which has a steep temperature dependence, , and (b) the assumed rapid perpendicular transport in the plasma bulk which, in experiments to date, may be due to the small number of ion gyroradii across the plasma.

磁場反転配位(FRC)と捕捉された逆バイアス磁場を有するシータピンチは、本質的に、開放端磁束管内の閉磁力線を利用する同じ磁気閉じ込め系である。ジュール加熱と外部熱浴への開放磁力線に沿った平行電子熱伝導の単純なモデルは、電子温度をTe(eV) ≅ 0.05 B2/3(G) L1/3(cm)として与える。ここで、Bは磁場、Lはコイル長である。このモデルは、40〜900 eVの範囲をカバーする現在のFRC実験および過去のシータピンチ実験からの測定値と一致するように思われる。このモデルのエネルギー収支は、(a)急峻な温度依存性を持つ開放磁力線に沿った平行電子熱伝導、および(b)プラズマバルクにおける想定される高速の垂直輸送によって支配される。後者は、これまでの実験では、プラズマ横断方向のイオンジャイロ半径の数が少ないことに起因する可能性がある。
