Here, EC-driven current is generated by EC heating of the suprathermal electron beam in OH plasma. Further, when P_EC is injected into plasma sustained by lower-hybrid- (LH-) driven current, the plasma current and its rampup rate increase. Here, EC-driven current is generated by EC heating of the mildly relativistic electrons in LH-driven plasma.}, pages = {2180--2183}, title = {Plasma Current Generation and Sustainment by Electron Cyclotron Waves in the WT-2 Tokamak}, volume = {56}, year = {1986} }
