摘要:

利用自行设计的快速移动静电探针对大气压下以氩气为工质的大尺度磁分散电弧等离子体进行诊断,分析了探针电压与电流的波形,绘制探针伏安特征曲线(U-I曲线),得到了发生器轴线方向等离子体波动特性以及电子温度沿轴线的变化趋势。发现等离子体发生器中心具有回流区,得到了电弧等离子体的大致体积。

Abstract:

The fast-moving electric probe designed by ourselves is used to diagnose the large-scale magnetically rotating arc plasmas in the argon under the atmospheric pressure. The signal shape of the voltage and current of the electric probe is analyzed to draw the U-I curve. The fluctuation characteristic of the plasmas on the axis of the generator is obtained, and the axial distribution of the electron temperature on the axis of the generator is found. It is found that there is a recirculation zone in the center of the generator, and the approximate volume of the arc plasmas is got.

Key words: Electric probe, Large-scale, Magnetically rotating arc, Plasmas, Electron temperature
