Abstrakt: An analysis is made of the transition to improved confinement (H-mode) observed in lower hybrid heating experiments in the FT-2 tokamak. Particular attention is paid to processes taking place near the wall, including the suppression of microfluctuations accompanying the L-H transition and the buildup of edge-localized modes (ELM activity). The conditions for transition to the H-mode are discussed only for Ohmic heating. The data are compared with the results of large tokamak experiments. [ABSTRACT FROM AUTHOR]
