Abstract
The interaction of high power lower hybrid waves with tokamak plasma result s in a range of favourable but also unfavourable effects. This article deal s with the effects observed by Langmuir probes on the small tokamak CASTOR. The most pronounced effects found are positive biasing of the whole plasma periphery and the formation of a negative "well" of floating potential in front of the launcher.
