高温等离子体螺旋形放电研究取得了重大进展。由于壁面循环减少，中心离子温度明显升高。离子加热谱的峰化和高能离子电荷交换损失的降低，对进一步改善离子内输运势垒（ITB）核中的离子热输运具有重要意义。离子ITB和电子ITB由于中心聚焦的电子回旋加速器加热叠加在离子ITB等离子体上而成功地集成在一起，并且离子温度与电子温度（Ti ~ Te）相当的高温区得到了显著的扩展。与电子ITB形成的离子ITB的宽度比电子ITB的宽度宽。重离子束探针在集成ITB等离子体中观察到正的径向电场，而在离子ITB等离子体中观察到负的径向电场。离子温度梯度随温度比（Te /Ti）的增大而减小。
The discharge scenario of high temperature plasma with a helical configuration has significantly progressed. The increase of central ion temperature due to the reduction of wall recycling was clearly observed. The peaking of the ion heating profile and the reduction of charge exchange loss of energetic ions play an important role for further improvement of ion heat transport in the ion internal transport barrier (ITB) core. The ion ITB and electron ITB have been successfully integrated due to the superposition of centrally focused electron cyclotron heating to the ion ITB plasma, and the high temperature regime of the ion temperature comparable to the electron temperature (Ti ~ Te) has been significantly extended. The width of the ion ITB formed with electron ITB is wider than the width of electron ITB. The positive radial electric field was observed in the integrated ITB plasma by a heavy ion beam probe, while the negative radial electric field was observed in ion ITB plasmas. The ion temperature gradient decreases with the increase of the temperature ratio (Te /Ti).
