Abstract

By injecting the lower hybrid wave (LHW) into the microwave discharge at the electron cyclotron (ec) resonance in the WT-2 toroidal device, the plasma current is started up and sustained by rf power alone (rf tokamak). Here the high energy electrons are generated initially by ec heating, then accelerated resonantly with LHW and the plasma current is carried by the high energy electron tail. Temporal and spatial evolutions of this high energy electron tail are studied by soft and hard X-rays emitted from the rf tokamak plasma.
