要約(英語): Transient effect of magnetic reconnection has been investigated in the TS-4 torus plasma merging device. The two loop merging with pull reconnection converts one common flux to two private fluxes. Under strongly driven inflow, the plasma and magnetic flux inflow exceeded the outflow ones, causing flux and density piled-up in the current sheet. This pile-up effect was found to increase the inflow speed without anomalous resistivity effect. Under strong guiding field, a plasmoid grew in the current sheet during plasma pile-up. When flux pile-up reached a critical value, the plasmoid was ejected from the reconnection region and the reconnection speed transiently increased. The plasmoid ejection made the reconnection rate maximum when its acceleration was maximized.
