Theoretical studies of the formation and adiabatic compression of reversed-field configurations in imploding liners

The formation and compression of e-beam-induced reversed-field theta-pinch configurations are studied theoretically in an MHD treatment. Taking into account classical collisional resistivity plus anomalous resistivity derived from microinstabilities, it is shown that plasmas can be created with parameters suitable for liner compression experiments. Adiabatic compression of the quasi-equilibrium plasma/flux mixture is described by using Lagrangian co-ordinates. Results are given for a sample (unoptimized) initial configuration. In the final state, the ratio of plasma to total energy and the total D-T rate are 30% and 20%, respectively, of the values which would be obtained if all the compressional energy went into heating plasma,i.e. assuming negligible magnetic-field-filled volume.

電子ビーム誘起反転磁場シータピンチ配位の形成と圧縮を、MHD 処理において理論的に研究する。古典的衝突抵抗率と、微視的不安定性に由来する異常抵抗率を考慮に入れると、ライナー圧縮実験に適したパラメータを持つプラズマが生成され得ることが示される。準平衡プラズマ/磁束混合体の断熱圧縮は、ラグランジュ座標を用いて記述される。サンプル(未最適化)初期配位に対する結果が示される。最終状態では、プラズマエネルギーと全エネルギーの比および全 D-T 反応率は、すべての圧縮エネルギーがプラズマ加熱に費やされた場合、すなわち磁場充填体積が無視できると仮定した場合に得られる値の、それぞれ 30% および 20% となる。
