STATUS OF THE ECRH SYSTEM ON HL-2A
this work partially supported by Core-University Program on Plasma and Nuclear Fusion.
3MW ECRH system with six 68GHz/500kW gyrotrons has been developed on HL-2A. H mode discharges have been realized with ECRH and NBI. NTM has been observed during ECRH heating. Transient ITB after ECRH switch-off has been achieved. Stabilization of tearing mode and sawtooth control with ECRH has been studied
