Electron energy transport in field reversed configuration (FRC) equilibria is studied experimentally for a variety of conditions. Up to 37% of the global plasma power loss is attributed to non-convective processes by electrons. The electron temperatures are approximately two times larger than those measured without reversed bias field, which indicates confinement by the poloidal magnetic field in the FRC. The inferred average cross-field thermal diffusivities χ⊥e are anomalous, ranging between 35 and 140 times classical, and are consistent with transport from turbulent magnetic fluctuations of 1 to 2%.

電界反転配位(FRC)平衡における電子エネルギー輸送を、多様な条件下で実験的に研究した。全プラズマ電力損失の最大37%が、電子による非対流過程に起因することが明らかになった。電子温度は、反転バイアス磁場なしで測定された値の約2倍であり、これはFRCにおけるポロイダル磁場による閉じ込めを示している。推定された平均横断熱拡散係数χ⊥eは異常であり、古典値の35倍から140倍の範囲にあり、1〜2%の乱流磁場揺らぎによる輸送と一致している。
