Measurements of ion and electron temperatures on REPUTE-1 ultra-low q (ULQ) and reversed field pinch (RFP) plasmas have revealed that the ion temperature is higher than the electron temperature and that the impurity ion temperature exceeds the hydrogen ion temperature. In ULQ plasmas the impurity ion temperature is correlated with the amplitude of the magnetic field fluctuations observed outside the plasma. A model on ion heating by fluctuations is found to explain the experimental results.

REPUTE-1の超低q(ULQ)および逆転磁場ピンチ(RFP)プラズマにおけるイオン温度と電子温度の測定により、イオン温度が電子温度よりも高く、不純物イオン温度が水素イオン温度を超えることが明らかになった。ULQプラズマにおいて、不純物イオン温度はプラズマ外部で観測される磁場変動の振幅と相関がある。変動によるイオン加熱に関するモデルが実験結果を説明することが見出された。
