Abstract: | A tangentially visible imaging system has been developed on the Experimental Advanced Superconducting Tokamak(EAST) to record the full cross-section plasma visible radiation with speed up to 7500 frames per second at full resolution or much faster for a limited number of pixels.The edge localized mode(ELM) filaments during ELM eruptions in H-modes are captured.Using these pictures,the current in the filament is estimated. |
