HT-6M中性注入加热电荷交换能谱分析

ANALYSIS OF CHARGE-EXCHANGE SPECTRA DURING NBI HEATING IN THE HT-6M TOKAMAK

用电荷交换中性粒子能谱分析的方法,研究了HT-6M托卡马克中性注入加热期间的氢离子能谱,得到了离子温度的增加。测量结果与实验定标律的估算在误差范围内相符;并与根据Fokker-Planck方程计算的注入过程中的离子能谱和温度变化进行了比较。

Hydrogen ion energy spectra during NBI heating were investigated by energy analysis of charge-exchange neutral particle. The results indicate that ion temperature has been increased. The rise of ion temperature is in agreement with the values calculated by the method of the empirical scaling law.The Fokker-Planck equation is used to calculate charge-exchange spectra and ion temperature, and compare them with the experiment results.
