Abstract
It is found on KT-SC tokamak that an edge fluctuation mode can be exci ted by using a pair of floating Langmuir probes. This mode is propagat ing along the magnetic field with its amplitude decreasing drastically when it is off the magnetic field line. Preliminary feedback experime nts door that the broadband edge turbulence can be reduced or enhanced depending upon the phase shift of the feedback network.
