抄録

Magnetic fluctuations at a frequency lower than the local ion cyclotron frequency have been observed in association with magnetic reconnection events in a TS-3 plasma merging device. Counter-helicity merging of spheromaks provides significant ion heating by magnetic reconnection to form a high-β field-reversed configuration plasma. The magnitude of the fluctuation observed during and after the counter-helicity merging has a stronger dependence on the ion mass than on the reconnection speed, indicating that fast ion outflow from the X point would bring about excitation of large-amplitude low-frequency magnetic fluctuations, which may be responsible for direct ion heating.
