Long pulse plasmas, up to 400 s, were obtained by LHCD. High power lower hybrid wave （LHW）, with PLHW of 800 kW at 2.45 GHz, was launched and the current drive efficiency was studied for different wave powers. Electron temperature and Zeff were measured in LHCD discharges. Heating experiment and recent results of high power ion Bernstein wave, with PIBW of 600 kW at 27 MHz, were summarized.展开更多
