Abstract
Plasma rotation can lead to excitation of ship waves that have zero frequency in the laboratory frame. Ship waves of a drift type that have a global structure of a quasimode in a poloidally rotating toroidal plasma are considered for an axisymmetric, large aspect-ratio tokamak with concentric, circular magnetic surfaces. The analysis performed is based on rigorously derived eigenmode equations, coupled in poloidal mode numbers through the toroidal effects. Analytical dispersion relations for global drift ship waves are obtained and their simple solutions are found for some limiting cases. These global ship waves, resonantly excited due to a plasma rotation near the plasma edge, may give a simple explanation for the observed phenomenon of the fast response of the electron transport over a wide radial region in transitions from the low (L) to high (H) confinement regime (L–H transitions).
