Abstract

The possibility to control the transport processes in an LH-heated tokamak plasma has been demonstrated. The paper presents experimentally observed transport barrier formation, initialised by the LH heating. The effects of the improved confinement are observed by the Thomson scattering diagnostics, the CX analyser, diamagnetic, spectroscopic, bolometer, reflectometer movable multielectrode Langmuir and MHD probes measurements. Mechanisms for internal (ITB) and external transport barrier (ETB) formation have been put forward to explain the observed regime of improved core confinement. The increased shear of the radial electric field stimulates the improved core confinement (ICC) regime and a transition to the H-mode.
