Gyrokinetic Particle Simulation of Compressional Electromagnetic Modes
A gyrokinetic particle simulation model is developed for simulations of the compressional electromagnetic turbulence driven by the mirror instability. Results of the linear simulations of mirror modes agree well with the analytic dispersion relation. Nonlinear simulations of a single mode find that the mirror instability saturates via a phase-space trapping due to the nonlinear wave-particle in...
متن کاملGyrokinetic �f particle simulation of trapped electron mode driven turbulence
The linear instabilities and nonlinear transport driven by collisionless trapped electron modes �CTEM� are systematically investigated using three-dimensional gyrokinetic �f particle-in-cell simulations. Scalings with local plasma parameters are presented. Simulation results are compared with previous simulations and theoretical predictions. The magnetic shear is found to be linearly stabilizin...
متن کاملElectromagnetic formulation of global gyrokinetic particle simulation in toroidal geometry
The fluid-kinetic hybrid electron model for global electromagnetic gyrokinetic particle simulations has been formulated in toroidal geometry using magnetic coordinates, providing the capabilities to describe low frequency processes in electromagnetic turbulence with electron dynamics. In the limit of long wavelength and no parallel electric field our equations reduce to the ideal magnetohydrody...

متن کاملGyrokinetic Simulation of Energetic Particle Turbulence and Transport
The fully self-consistent simulation of energetic particle turbulence and transport in burning plasmas such as ITER must incorporate three new physics elements: (i) kinetic effects of thermal particles at the thermal ion gyroradius (micro scale), (ii) nonlinear interactions of many meso scale (energetic particle gyroradius) shear Alfvén waves induced by the kinetic effects at the micro scale, a...
