Enhanced confinement has been achieved by the centre fuelling of pellet injection on the HL-2A tokamak. The energy confinement time increases from 50 ms to 140 ms after the pellet injection. Experimental results show that the improvement of the confi

The main topics concerning lower hybrid wave heating (LHH) and lower hybrid current drive (LHCD) in tokamak systems are presented. The inherent properties of tokamak systems give the `gap' filling on Brambilla's spectrum, which are conducive to LHCD,
