摘　　要：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。おn the lower hybrid current drive (LHCD) experiments, the fast electrons driven by the wave are very important for understanding the lower hybrid current drive physics. Electron cyclotron emission (ECE) spectra have been measured in the LHCD experiments on the HL1M tokamak by means of a 2mm microwave scanning heterodyne receiver. To analyze the experimental spectra, several theoretical ECE spectra have been calculated. By comparing the theoretical calculation results with the experiment data, the energy distribution of fast electrons can be obtained. The behavior of fast electrons in the LHCD plasma in the HL1M tokamak have been investigated by these methods.
