RF experiments and future plan on Superconducting tokamak HT-7 and EAST

Research on HT-7 tokamak focuses on exploiting the IBW-heated plasmas mainly to understand heating, active control of profiles and the synergetic interaction with LHCD. Both on-axis and off-axis electron heating with global peaked and localize steep electron pressure profile were realized. The operation of IBW and LHCD synergetic discharges were obtained and optimized through moving the IBW resonant layer to maximize the plasma performance and to avoid MHD activity. Experimental Advanced Superconducting Tokamak (EAST) has been built to perform advanced tokamak research in high performance regime and to explore methods for achieving a steady-state operation for a tokamak fusion reactor at ASIPP. This talk reports an overview of ICRF wall conditioning in HT-7 and EAST during recent campaigns.
