本文报道了离子回旋频率范围(ICRF)加热在大型螺旋装置(LHD)上产生的高能离子的行为。在1999年进行的第三次实验活动中，发现少数加热具有良好的加热性能，并观察到高能粒子。在2000年的第四次活动中，利用ICRF功率的关闭或调制，研究了少数加热区域中高能离子的时间行为。使用天然钻石探测器(NDD)和飞行时间中性粒子分析仪(TOF-NPA)测量了高能粒子分布的时间演变。研究发现，在ICRF关断后，高能粒子的计数下降速度快于低能粒子。在调制实验中，高能粒子磁通相对于ICRF功率调制的相位差随着能量的增加而增大。用Fokker-Planck方程和一个简单的模型定性地解释了这些结果。实验中还通过改变TOF-NPA的视线测量了分布函数的俯仰角依赖关系，发现了高能尾部的各向异性。这种各向异性是通过求解弹跳平均福克-普朗克方程来再现的。在高β等离子体中，首次在铲运机中成功地进行了二次谐波加热，并在此加热区域内探测到高能粒子。
This paper reports on the behaviour of high-energy ions created by ion cyclotron range of frequency (ICRF) heating on the Large Helical Device (LHD). In the third experimental campaign conducted in 1999, it was found that minority heating has good heating performance, and high-energy particles were observed. In the fourth campaign in 2000, the temporal behaviour of high-energy ions was investigated in the minority heating regime using turnoff or modulation of ICRF power. The time evolution of the high-energy particle distribution was measured using a natural diamond detector (NDD) and a time-of-flight neutral particle analyser (TOF-NPA). It was found that the count number of higher-energy particles declines faster than that of lower-energy particles after ICRF turnoff. In the modulation experiments, the phase difference of the flux of high-energy particles with respect to the ICRF power modulation increased with energy. These results were explained qualitatively by the Fokker-Planck equation with a simple model. The pitch-angle dependence of the distribution function was also measured in the experiment by changing the line of sight of the TOF-NPA, and an anisotropy of the high-energy tail was found. This anisotropy was reproduced by solving the bounce-averaged Fokker-Planck equation. The second harmonic heating was conducted successfully for the first time in the LHD in high-β plasma, and high-energy particles were also detected in this heating regime.
