Abstract

In the HT-7 superconducting tokamak, long-pulse discharge was generated by synergy of high power LHCD (300-600 kW, 2.45 GHz) and high power IBW (200-350 kW, 27 MHz) heating. Recently, a new set of actively cooled toroidal double-ring graphite limiters at bottom and top of the vacuum vessel has been developed for long-pulse operation in the HT-7. Based on the understanding of plasma surface interactions, nearly full non-inductive current driven plasma (I_p = 120-180 kA, B_T = 1.5-2 T, T_e(0) = 2-4 keV, and 〈n_e〉 = 1-2.5 × 10¹⁹ m^-3) was achieved with the operational pulse length of 1-10 s. For lower performance operation, more than 60 s of long-pulse plasma was obtained by the LHCD in 2003 on the HT-7 tokamak.
