摘要：

The interaction between a powered ICRH antenna and plasma scrape-off layer is investigated by Langmuir probes. When a reciprocating Langmuir probe is magnetically connected to a powered ICRH antenna, large RF-induced potentials are observed along the entire leading edge of the antennaSs poloidal protection limiters. Recent experiments show that a key parameter affecting the amplitude of these potentials is plasma density. The detailed 2D map of the potentials induced in front of the ICRH antenna is presented as well as the influence of the density on these potentials and parallel flow.
