The algorithm has been carried o ut within the S ymPIC code, which is designed for high-efficiency massively-parallel PIC simulations in fashionable clusters. The code has been applied to hold out whole-device 6D kinetic simulation studies of tokamak physics. A self-consistent kinetic regular state for fusion plasma within the tokamak geometry is numerically discovered with a predominately diagonal and anisotropic strain tensor. The state additionally admits a steady-state sub-sonic ion move within the range of 10 km s−1, agreeing with experimental observations and analytical calculations Kinetic ballooning instability in the self-consistent kinetic regular state is simulated. It is proven that high-n ballooning modes have larger progress rates than low-n world modes, and within the nonlinear part the modes saturate approximately in 5 ion transit times at the 2% degree by the E × B circulate generated by the instability. These outcomes are in preserving with early and up to date ele
