Propagation and damping of mode converted ion‐Bernstein waves in toroidal plasmas

Experimental observation of ion heating by mode- converted ion Bernstein waves in tokamak plasmas

We report the experimental observation of ion heating by the mode-converted ion Bernstein waves (MC IBWs) in tokamak plasmas. The MC IBW is created from the fast waves launched from the high-field-side antenna in the HT-7 tokamak in plasmas consisting of deuterium majority, hydrogen minority and 7Li ions. Experimental evidence and numerical simulation show that the interaction between the MC IB...

Kinetic Theories of Geodesic Acoustic Mode in Toroidal Plasmas

Geodesic Acoustic Modes (GAM) are known to constitute a continuous spectrum due to radial inhomogeneities. The existence of a singular layer causes GAM to mode convert to short wavelength kinetic GAM (KGAM) via finite ion Larmor radius (FLR) and finite guiding-center drift-orbit-width (FOW) effects. The dispersion relation of GAM/KGAM with FLR/FOW as well as parallel electric field contribution...

Relativistic Landau damping of longitudinal waves in isotropic pair plasmas

Ultrahigh resolution simulations of mode converted ion cyclotron waves and lower hybrid waves

Full Wave studies of mode conversion (MC) processes in toroidal plasmas have required prohibitive amount of computer resources in the past because of the disparate spatial scales involved. The TORIC code [1] solves the linear sixth order reduced wave equation for the ion cyclotron range of frequencies (ICRF), in toroidal geometry using a Fourier representation for the poloidal dimension and fin...
