Progress of LHCD and IBW Heating Experiments on HT-7 Tokamak

摘要

Experimental progress of lower hybrid current drive(LHCD)and ion Bernsteinwave(IBW)heating was achieved significantly in HT-7.Long pulse plasmas,up to 400 s,wereobtained by LHCD.High power lower hybrid wave(LHW),with P_(lhw)of 800 kW at 2.45 GHz,was launched and the current drive efficiency was studied for different wave powers.Electrontemperature and Z_(eff)were measured in LHCD discharges.Heating experiment and recent resultsof high power ion Bernstein wave,with P_(ibw)of 600 kW at 27 MHz,were summarized.
