Theoretical studies of this heating has been done in rather early literatures, however, the understanding of some important problems is still uncertain. These include: the coupling of the O-mode and the E-mode and the role of this coupling in wave damping, the O-mode damping mechanism,展开更多

Routinely, the ohmic heating can provide a heating power about 300-450 kW in this device （ estimated from that the total toroidal current is about 300 kA while the totoidal voltage is 1-1.5 V）. The total power for the ECRH now is 1 MW and in future 2 MW.展开更多
