Microwave beam broadening due to turbulent plasma density fluctuations within the limit of the Born approximation and beyond
Alf Köhn, Lorenzo Guidi, Eberhard Holzhauer +4
Plasma turbulence, and edge density fluctuations in particular, can under certain conditions broaden the cross-section of injected microwave beams significantly. This can be a seve…
Linear gyrokinetic investigation of the geodesic acoustic modes in realistic tokamak configurations
I. Novikau, A. Biancalani, A. Bottino +7
Geodesic acoustic modes (GAMs) are studied by means of the gyrokinetic global particle-in-cell code ORB5. Linear electromagnetic simulations in the low electron beta limit have bee…
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…
