Perturbing microwave beams by plasma density fluctuations
Alf Köhn, Eberhard Holzhauer, Jarrod Leddy +2
The propagation of microwaves across a turbulent plasma density layer is investigated with full-wave simulations. To properly represent a fusion edge-plasma, drift-wave turbulence…
Kinetic simulations of X-B and O-X-B mode conversion and its deterioration at high input power
A. V. Arefiev, I. Y. Dodin, A. Köhn +4
Spherical tokamak plasmas are typically overdense and thus inaccessible to externally-injected microwaves in the electron cyclotron range. The electrostatic electron Bernstein wave…
Influence of plasma turbulence on microwave propagation
Alf Köhn, Eberhard Holzhauer, Jarrod Leddy +2
It is not fully understood how electromagnetic waves propagate through plasma density fluctuations when the size of the fluctuations is comparable with the wavelength of the incide…
Kinetic simulations of X-B and O-X-B mode conversion
A. V. Arefiev, E. J. Du Toit, A. Köhn +3
We have performed fully-kinetic simulations of X-B and O-X-B mode conversion in one and two dimensional setups using the PIC code EPOCH. We have recovered the linear dispersion rel…
