Abstract

High frequency gyrokinetic (HFGK) algorithm for particle-in-cell (PIC) simulation has been developed based on the gyrocenter-gauge kinetic theory. This new algorithm takes advantage of the separation of gyrocenter and gyrophase motions introduced by the gyrokinetic formalism. The 6D version of the algorithm is equivalent to the direct 6D Lorentz-force simulation in the limit of small gyroradius (compared to the ambient magnetic field). Since the gyrocenter dynamics is slow, one is allowed to use large time step for pushing gyrocenters in the 6D HFGK algorithm, which results in saving in computing time. Using simple electrostatic collisionless system in slab geometry, we perform nonlinear PIC simulation of the ion cyclotron instability and nonlinear ion perpendicular heating dynamics using new 6D HFGK algorithm. Comparisons with a conventional 6D Lorentz-force code are presented.
