Gyrokinetic Particle Simulation of FInite Beta Microturbulence in Tokamak Plasmas

Recent progress in gyrokinetic simulations of plasma microturbulence using GTC code is reported. Verification of the fluid-kinetic hybrid electron model is done by running simulations at different values of $\beta_e$ using Cyclone base case parameters. Finite-beta stabilization, and transition from ITG to CTEM and later to the KBM mode is observed. The cross-code benchmark of real frequency and growth rate is done demonstrating good agreement.
