Abstract

Study on the characters of energy confinement in both ohmic and Lower Hybrid Wave (LHW) discharges on EAST is conducted and the linear ohmic confinement (LOC), saturated ohmic confinement (SOC) and improved ohmic confinement (IOC) regimes are investigated in this paper. It is observed that an improved confinement mode characterized by both a drop of Dα line intensity and an increase in line average density can be triggered by a gas puffing pulse.
