Beyond the Greenwald Density Limit on EAST

“**Exceeding the Greenwald Density Limit via Plasma-Wall Self-Organization (PWSO):** "In the recent breakthrough experiments on the EAST tokamak, how did researchers leverage Electron Cyclotron Resonance Heating (ECRH)-assisted startup and tungsten plasma-facing components to suppress impurity-dominated physical sputtering, successfully driving line-averaged electron densities to $1.65 n_G$ and ent”
