The effect is considered of magnetic fluctuations on electron heating of tokamak plasmas by lower hybrid waves. For high power experiments, magnetic fluctuations can enhance both the electron heating rate and the anomalous loss rate. Each of these effects can reduce the efficiency of bulk electron heating; the outward shift in power deposition can increase losses even with the same transport rate, and the RF enhanced anomalous transport can provide a significantly increased loss rate.
磁気揺動が低域混成波によるトカマクプラズマの電子加熱に及ぼす影響について考察する。高出力実験では、磁気揺動は電子加熱率と異常損失率の両方を増大させ得る。これらの各効果はバルク電子加熱の効率を低下させ得る。すなわち、電力堆積の外向きシフトは、輸送率が同じでも損失を増大させ得る一方、RF強化による異常輸送は、損失率を有意に増大させ得る。
