| Research Abstract |
A novel technique measuring the propagation of plasma ejected intermittently in the high-confinement mode plasma(ELM pulse) has been developed, utilizing the motional Stark effect diagnostics that measure current profile in the fusion plasma. With this new technique, it has been found that the propagation velocity of the ELM pulse in the major radius direction is faster for ELM pulses having larger energy ejected from plasma with larger plasma current. It has also been found that the velocity of the ELM pulse increases with increase in the distance from the plasma surface.
