| 英文摘要 | Synergistic effects between two frequencies of lower hybrid (LH) waves-operating at 2.45 and 4.6GHz-were observed in experiment on EAST for the first time. At low density (n(e,lin) approximate to 2.0 x 10(19) m(-3)), simultaneous injection of a 65/35 mix of 2.45/4.6GHz power achieved an lower hybrid current drive efficiency that was 25% higher than what should be expected from the linear combination of the two sources. The experiment was interpreted with time-dependent simulations, using the equilibrium and transport solver TRANSP, coupled with the ray-tracing code GENRAY and the Fokker-Planck solver CQL3D. For each discharge, profiles of current and hard x-rays from simulation and measurement agree within uncertainties. An examination of the electron distribution function indicates that the LH synergy is supported by the increased width of the LH resonance plateau in the simultaneous injection case compared to independent injection. |
