On effects of a local plasma density growth due to ponderomotive forces at fast wave launching in tokamaks

Creators

Description

Nonlinear changes of the reflection coefficient at fast wave launching by a waveguide array are computed also for the case of an eventual fast wave experiment on the FTU tokamak. In case of low plasma density gradients, the reflection coefficient may significantly change for the wave power in the range of several kilowatts per centimeter square due to ponderomotive force effects.
