  • The effect of resonant magnetic perturbation (RMP) on boundary turbulence and transport in J-TEXT plasma is experimentally investigated. Edge plasma fluctuations in discharges with and without the (m/n=3/1) RMP currents are diagnosed by using Langmuir probe arrays. It was found that fluctuations in the edge and scrape-off layer (SOL) regions decrease with the application of a 6 kA RMP. The broadband turbulence at the radial location of ρ ~ 0.9 which has a characteristic frequency of 40–150 kHz was strongly suppressed when applying RMP, as was the radial turbulent particle flux and blob transport in the near-SOL region. These experimental findings make RMP a promising method of suppressing and controlling turbulence and particle transport in a plasma boundary.
