Reduction of Mixing-Length Transport by Radio Frequency Waves

Numerical simulation is carried out by using the ASTRA code to determine the effect of mixing-length transport induced in a plasma in the presence of radio-frequency waves. It is found that the transport coefficients associated with particle diffusion and heat diffusion reduce drastically in the region where radio waves is launched. This technique opens up a new avenue of transport suppression by the use of radio waves of suitable frequency.
