Relativistic effects in millimeter wave applications on magnetically confined plasmasFunded under: EAEC-FUSION 12C
Relativistic treatment is essential for detailed models of absorption and emission of electron cyclotron waves. The significance of relativistic effects on millimetre waves is illustrated by the fact that, in the range of parameters relevant to X-mode reflectometry on large tokamaks, the relativistically predicted R-cutoff density is typically 30 % higher than the non-relativistic prediction. A number of approximations to the relativistic dielectric tensor are compared for the efficiency of computation and range of validity, with a view to the routine need for such calculations in Next Step devices.
