In an additional heating experiment on translated theta-pinch produced field reversed configuration (FRC) plasma with density of 5 × 1019m−3 and pressure balance temperature of 100 eV by 10 keV hydrogen neutral beams, only electrons are observed to be heated; electron temperature is controlled independently of ion temperature for the first time ever in FRC plasma. So far, the confinement times of the FRC plasma were known to depend approximately on (rs, separatrix radius, ρi0, ion gyro radius) and dependence on electron temperature was small; this is confirmed by the present experiment. The FRC plasma is also produced and sustained for longer than 4 ms by a rotating magnetic field (RMF) in a metal confinement chamber. The performance of the present RMF-produced FRC plasma is low with density and temperature less than 5 × 1017m−3 and 10 eV, respectively. The efficiency of the FRC plasma production by the RMF is found to be higher for higher RMF frequencies.

並進シータピンチにより生成された電場反転配位(FRC)プラズマ(密度5 × 10¹⁹m⁻³、圧力平衡温度100 eV)に対し、10 keV水素中性粒子ビームによる追加加熱実験を行ったところ、電子のみが加熱されることが観測された。電子温度は、FRCプラズマにおいて史上初めてイオン温度とは独立に制御された。これまでFRCプラズマの閉じ込め時間は近似的に(rs、セパラトリクス半径、ρi0、イオンジャイロ半径)に依存し、電子温度への依存性は小さいことが知られていたが、本実験によりこれが確認された。また、FRCプラズマは金属閉じ込め容器内で回転磁場(RMF)により4 ms以上にわたって生成・維持された。本RMF生成FRCプラズマの性能は低く、密度は5 × 10¹⁷m⁻³未満、温度は10 eV未満であった。RMFによるFRCプラズマ生成効率は、RMF周波数が高いほど高いことが見出された。
