在低混杂电流驱动（ＬＨＣＤ）实验中，研究由波驱动的快电子的行为对理解低混杂波驱动物理是十分重要的。在ＨＬ－１Ｍ装置上，用２ｍｍ波段（１１７—１８２ＧＨｚ）扫频外差辐射机，测量了在ＬＨＣＤ条件下等离子体的电子回旋辐射（ＥＣＥ）谱。通过理论计算以及与实验数据的比较，能得到高能电子的能量分布等参数。用该方法对ＨＬ－１Ｍ装置上的ＬＨＣＤ等离子体中的快电子行为进行了研究。
In LHCD experiments, it is very important to study the behavior of fast-electrons driven by waves in order to understand the physics of low-noise hybrid driving. The electron cyclotron emission (ECE) spectrum of the plasma under LHCD conditions was measured on a HL-1M device using a 2mm band (117-182GHz) frequency-swept heterodyne radiator. By theoretical calculation and comparison with experimental data, we can get the energy distribution and other parameters of high-energy electrons. The fast electron behavior in LHCD plasmas on HL-1M devices was investigated using this method.
