Global gyrokinetic simulation of Tokamak edge pedestal instabilities.

Global electromagnetic gyrokinetic simulations show the existence of near threshold conditions for both a high-n kinetic ballooning mode (KBM) and an intermediate-n kinetic version of peeling-ballooning mode (KPBM) in the edge pedestal of two DIII-D H-mode discharges. When the magnetic shear is reduced in a narrow region of steep pressure gradient, the KPBM is significantly stabilized, while th...

Electron fishbone simulations in tokamak equilibria using XHMGC

This paper discusses the first nonlinear numerical simulation results of fishbone excitation by a magnetically trapped supra-thermal electron population with pressure profile peaked on axis due to, e.g. electron cyclotron resonance heating. The precession resonance underlying the linear instability is clearly identified. Meanwhile, mode saturation is shown to occur because of the secular resona...

Drift Ballooning Instabilities in Tokamak Edge Plasmas

The linear stability of high-toroidal-number drift-ballooning modes in tokamaks is investigated with a model that includes resistive and viscous dissipation, and assumes the mode frequency to be comparable to both the sound and diamagnetic frequencies. The coupled effect of ion drift waves and electron drift-acoustic waves is shown to be important, resulting in destabilization over an intermedi...

Investigations of Magnetohydrodynamic Instabilities in the STOR-M Tokamak

Studies of magnetohydrodynamic (MHD) instabilities in the Saskatchewan Torus-Modified (STOR-M) tokamak have been conducted to examine the mode structures and time evolution during the Ohmic discharges and after compact torus (CT) injection. External discrete Mirnov coils and two pin-hole soft x-ray (SXR) cameras have been used for the studies. The time-resolved frequency component analysis has ...
