一台新的１０道电荷交换中性粒子能谱仪已用于ＨＴ７托卡马克装置等离子体测量．它具有磁场和电场，且在能量０２—５０ｋｅＶ范围进行了标定．新的能谱仪对于电荷交换粒子测量既能质量分辨，又可能量分析，还能提供空间多点扫描．在欧姆加热氘放电期间，进行了较大角度范围内的径向扫描离子温度测量，得到了ＨＴ７托卡马克离子温度的时间和空间分布 A new 10-channel charge-exchange neutral-energy spectrometer has been used for plasma measurement of HT-7 tokamak devices. It has a magnetic field and an electric field, and is calibrated in the energy range of 0  2-50 keV. The new spectrometer for mass spectrometry of charge-exchange particles can not only quality analysis, but also the amount of energy analysis, but also provide spatial multi-point scan. During the discharge of ohmic heating deuterium, the radial scanning ion temperature measurement was carried out in a wide range of angles, and the time and space distribution of the temperature of HT-7 tokamak ions was obtained
