本文概述了微型环流器的几项电磁测量方法及其实验结果。利用磁探头测量了等离子体柱的位移,对等离子体平衡和稳定性作了进一步的观测。利用等离子体反磁测量得到T_e+T_i为36—50电子伏,τE约为80微秒。利用自制的参数测量仪测量了具有时间分辨的等离子体电导率与欧姆加热功率。由电导率及静电探针测量得到T_e约为20电子伏。由静电探针测量得到n_e约为10~(13)厘米~(-3)。 This article outlines several electromagnetic measurement methods and their experimental results for a micro-circulator. The displacement of the plasma column was measured by using a magnetic probe, and the plasma balance and stability were further observed. T_e + T_i is 36-50 electron volts measured by plasma diamagnetic measurement, and τE is about 80 microseconds. The time-resolved plasma conductivity and ohmic heating power were measured using a self-made parametric meter. Measured by conductivity and electrostatic probe, T_e is about 20 electron volts. Measured by electrostatic probe n_e about 10 ~ (13) cm ~ (-3).
