Dynamic characteristics of edge plasma profiles during the opening of edge islands on the J-TEXT tokamak
On the J-TEXT tokamak, the dynamics of edge magnetic topology during the opening of the Custom Shape Warm LED Night Light edge magnetic islands induced by the external Resonant Magnetic Perturbation (RMP) are investigated.The edge island chain is pushed outward by increasing plasma toroidal current to intersect the poloidally and toroidally localiz
