Recently, a series of stationary H-mode
plasmas have been achieved on the Chinese superconducting tokamak EAST. The H-mode campaign started on 14 September this year. The principal goals were to investigate the efficiency of radio frequency heating on minority hydrogen and the mode conversion scenario, and to explore existing capabilities for achieving H-mode plasmas and long-pulse plasma operations. Lithium wall conditioning has routinely been used to reduce both impurity and hydrogen recycling.
