Benchmark of Electromagnetic Gyrokinetic Codes in High Performance Fusion Plasma

Access this Article



<p>Benchmark between electromagnetic gyrokinetic codes GKV and GENE based on the flux tube model has been carried out by employing the high performance tokamak experiment data. The constructed flux coordinates, linear dispersion relation, and nonlinear turbulent transport show good agreements. Utilizing these codes, linear mode structures of micro-tearing modes have been examined. It is found that the current density is highly localized in the radial direction and peaks on the inner board side of the torus, while the broaden O-shape structure is observed on the torus outer board side. This broadening originates from the magnetic drift, that is, the finite orbit width of passing particles.</p>
