Abstract

The dynamics of the magnetic island formed inside the reconnection current layer was investigated under the strong guide field in the UTST spherical tokamak merging experiment. A pair of proximately located O- and X-points was generated at ∼5 cm away from the other X-point. The formed O- and X-points immediately started to move toward the downstream region inside the current layer, but the O-point had larger velocity and caught up the preceding X-point within 0.5 μs. The results from Doppler spectroscopy indicated that the ion flow velocity had the intermediate value between the O- and X-point velocities, suggesting that the ions flowed with approximately the same velocity with the magnetic island.
