Azimuthally non-uniform equilibrium of field-reversed configuration sustained by rotating magnetic field with spatial high-harmonic components

Field-reversed configurations (FRCs) sustained by rotating magnetic fields (RMFs) with spatial high-harmonic components have been studied in a metal flux conserver of the FRC injection experiment apparatus. In the RMF-FRC equilibrium, significant azimuthal variation of the axial magnetic field, the electron density and the electron rotation velocity are observed. This deformation of the core FRC plasma is brought about by the strong azimuthal non-uniformity of the RMF and the configuration is consistent with the continuity of the electron flow flux and the magnetic field reversal conditions. The RMF with spatial high-harmonic components provides quasi-steady current drive of high-beta and singly-connected FRC plasmas without destructive modes and will be helpful in reducing the particle loss and thermal load when applied to the fusion core plasma.

磁場反転配位(FRC)は、空間高調波成分を有する回転磁場(RMF)によって維持され、FRC入射実験装置の金属フラックスコンサーバー内で研究されてきた。RMF-FRC平衡状態において、軸方向磁場、電子密度、および電子回転速度の有意な方位角方向の変化が観測される。この炉心FRCプラズマの変形は、RMFの強い方位角方向の不均一性によって引き起こされ、その配位は電子流束の連続性および磁場反転条件と整合的である。空間高調波成分を有するRMFは、高ベータかつ単連結のFRCプラズマの準定常電流駆動を破壊的モードなしで提供し、核融合炉心プラズマに適用された場合、粒子損失および熱負荷の低減に役立つであろう。
