三探头 Si(Li)探测器对 HL-1M 装置中电子温度和重金属杂质线辐射谱测量

Measurement of Electron Temperature and Line Radiation of Heavy Metal Impurities Using Three Si(Li) Drift Detectors in HL 1M Tokmak

本文叙述了用三探头Ｓｉ（Ｌｉ）漂移探测器测量ＨＬ－１Ｍ托卡马克芯部等离子体辐射的软Ｘ射线能谱，得到等离子体温度及重金属杂质水平随时间变化，其时间分辨达５０ｍｓ，探测系统的测量范围１．２５～２５ｋｅＶ之间。

The time evolution of electron temperature and the impurity level of heavy metal are derived from soft X ray energy spectra detected by three Si(Li) drift detectors. The energy range of this detection system is between 1 25 to 25 keV, and the time resolution is 50 ms
