Energy Confinement of both Ohmic and LHW Plasma on EAST

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 improv...

Description
Summary: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 IDa line intensity and an increase in line average density can be triggered by a gas puffing pulse.
