在2 7 MHz、BO=2.0T的氢少子区实验先进超导托卡马克(EAST)上成功地进行了快波等离子体加热。在注入1 mW离子回旋频段功率、线平均电子密度为4.0×10 19m−3时，电子温度从1.0keV上升到2.0keV以上，回路电压下降。储能增加了30kJ。利用低杂波和射频加热相结合的方法，获得了第一个6.4H模的S等离子体。在高电子密度为4.0×10 19m−3的L模放电中观察到密度泵浦。在这些放电中，当施加ICRF功率时，观察到等离子体的再附着。
Plasma heating using fast waves was successfully performed on the Experimental Advanced Superconducting Tokamak (EAST) in the H minority regime in deuterium plasmas at 27 MHz and Bo = 2.0 T. With 1.0 MW of ion cyclotron range of frequency (ICRF) power injected at a line-averaged electron density of 4.0 × 1019 m−3, the electron temperature increased from 1.0 keV to above 2.0 keV and the loop voltage dropped. An increase in the stored energy by 30 kJ was obtained. The first H-mode plasma of 6.4 s was achieved with a combination of lower hybrid wave and ICRF heating. Density pump-out was observed during L-mode discharges at a high electron density of 4.0 × 1019 m−3. In these discharges, re-attachment of the plasma was observed when ICRF power was applied.
