Description

Amplified poloidal flux of spheromak has been observed in the repetitive discharge (50 kHz) of magnetized coaxial plasma gun (MCPG). In this experiment, ejected spheromak is confined within magnetic mirror configuration, and generated flux and emission has been measured. In the case of repetitive discharge, increased poloidal flux and its decay time compared to quasi-DC discharge has been observed. Also increased emission light and its decay time has been observed. These results indicates increasing of energy confinement time. In addition, global stabilization of behavior of spheromaks when it is transporting in discharge tube has been observed in repetitive discharge case. (author)
