Abstract

The amplitude and spatial phase of the intrinsic error field of Joint TEXT (J-TEXT) tokamak were measured by scanning the spatial phase of an externally exerted resonant magnetic perturbation and fitting the mode locking thresholds. For a typical plasma with current of 180 kA, the amplitude of the 21 component of the error field at the plasma edge is measured to be 0.31 G, which is about 1.8 × 10^-5 relative to the base toroidal field. The measured spatial phase is about 317° in the specified coordinate system (r, θ, ) of J-TEXT tokamak. An analytical model based on the dynamics of rotating island is developed to verify the measured phase.
