First measurements of the charge-exchange ion temperature in the Heliotron-E device are described. The limiting temperatures calculated from a simple energy balance equation are presented and compared with the measured temperatures. In low-current plasma, the measured temperatures agree well with the thermal conduction limit based on neoclassical theory, which includes an effect of the electron-to-ion temperature ratio Te/Ti. In high-current plasma, however, the ion temperature is about one-third of the limiting temperature. This discrepancy may be due to anomalous heat and particle transport driven by the plasma current.

ヘリオトロンE装置における電荷交換イオン温度の最初の測定について述べる。単純なエネルギー平衡式から計算された限界温度を示し、測定温度と比較する。低電流プラズマでは、測定温度は新古典理論に基づく熱伝導限界とよく一致し、この理論には電子対イオン温度比Te/Tiの効果が含まれる。しかし、高電流プラズマでは、イオン温度は限界温度の約3分の1である。この不一致は、プラズマ電流によって駆動される異常な熱および粒子輸送に起因する可能性がある。
