Abstract

EAST has demonstrated its capability of long pulse operation using RF heating (LHCD and ICRF) in past experiments. One key issue to realize the long pulse H-mode experiments is to sustain the plasma current for steady state operation. Based on the calculations of the transport code ONETWO and its coupled RF code GENRAY, two scenarios have been proposed to achieve the 10 s H-mode plasma with I_p=400 kA, < n_e >=4.5×10¹⁹ m^-3, β_N=2, and the 100 s H-mode plasma with I_p=280 kA, < n_e >=3.5×10¹⁹ m^-3, β_N = 1.8 recently. The current drive of lower hybrid wave is an important issue in the two scenarios. An experimental result on lower hybrid current drive in H-mode plasmas on EAST is also presented.
