Kinetic effects on electron cyclotron emission during electron cyclotron heating in tokamaks
Abstract
The properties of the radiation emitted by non-Mawellian distributions generated by high-power electron cyclotron plasma heating are studied. The electron distribution is determined by solving the time dependent bounce averaged quasilinear Fokker-Plank equation by means of a three dimensional Fokker-Plank code. The computed steady state distribution function is then used to calculate the emission and transmission spectra for different locations of the receiving antennas, polarizations, and harmonics. The results yield insights on the impact of quasi-linear flattening and electron trapping.
