| 摘 要： | 介绍了对HL-2A装置中平面边缘等离子体的单探针测量。单探针是安装在可径向移动、并可绕轴旋
转360o的传动杆上的。在1MHz的快速采样频率下,测量了主等离子体边缘的温度、密度、悬浮电位、空间电位、极
向等离子体流速的径向分布。测量的结果表明,利用单探针测量的主等离子体边缘参数与朗缪尔四探针测量结果
基本一致。

| Abstract: | Measurments of the HL-2A edge plasma near the mid-plane with a fast-speed single probe are presented in the paper. The Langmuir probe is mounted on a long shaft, which can be shifted radially and rotated circularly. The radial profiles of the plasma edge electron temperature, density, floating potential, spacing potential and poloidal flow velocities have been measured utilizing a 1MHz fast-sampling module. The results obtained show that radial profiles of the temperature and the density measured with the single probe are in agreement to those with a four-probe system. |
