| 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. |
