Abstract
Lower hybrid current drive (LHCD) experiments for investigating theinteraction between lower hybrid (LH) wave and residual dc electric field wereperformed in extensive plasma parameter ranges in the HT-7superconducting tokamak. The experimental results are well fitted to theKarney–Fisch theory on the efficiency of LH waves energyconverted to poloidal magnetic field energy. The fraction of absorbed LHpower is about 0.75 for the HT-7 machine, and the upshift of the LH-waveparallel refraction index during LHCD experiments have been derived bythe optimizing fitting parameters. The LH wave is also used for thetransformer recharging when the plasma current is maintained unchanged.The highest efficiency about 7% has been achieved in HT-7 machine.
