Effects of Rotation on Turbulent Transport in Field Reversed Configuration

The global field reversed configuration (FRC) geometry is incorporated in the gyrokinetic code GTC by using a field-aligned mesh in cylindrical coordinates, which enables the  global simulations coupling the FRC core and scrape-off layer (SOL) across the separatrix and from divertor to divertor. Magnetic function is used in the cylindrical coordinates to guarantee divergence-free of the magnetic field and to facilitate the construction of the global field-aligned mesh. This  global particle code has been successfully applied for linear drift wave simulation in FRC. Furthermore, a new space-charge 1D code for sheath simulation is developed, which can provide the boundary condition for the global simulation  with sheath effects and divertor biasing voltage. The effects of plasma rotation due to the external applied biasing voltage on the linear drift wave instability and transports are investigated in this work.
