Electron Density Behavior during Fast Termination Phase of Post-Disruption Runaway Plasma

抄録

Electron density behavior during the fast termination phase of the post-disruption runaway plasma was investigated for the first time. Increases in electron density after the rst drop of runaway plasma current were observed. At the second current drop, an increase in electron density with density oscillations having a period of ˜1 ms was found. After the second current drop, higher electron density was observed in the case of shorter current decay time.
