Abstract Text:
Turbulent transport is the dominant mechanism of transport in tokamaks, and is caused by micro-scale instabilities such as ITG and TEM modes. The impact of negative triangularity on these instabilities and their associated global nonlinear transport is not yet well-understood. We conduct total-f simulations with the global gyrokinetic code XGC in an electrostatic model to observe and characterize turbulent phenomena in the core of a pair of DIII-D-based model equilibria. We compare the nature of turbulent mode activity and fluxes between positive and negative triangularity mirror image equilibria. Full neoclassical effects are included self-consistently with turbulence physics. This work was supported by the DOE SciDAC program under Award Number DE-AC02-09CH11466.
