| Summary: | On the path towards energy breakeven in nuclear fusion reactors, great amounts of
research have also been invested in computational physics to create simulations that
allow for the simulation of the plasma conditions within a tokamak; but there is still much
more work to be done to create a reduced element model that can run within reason-
able computational resources and timeframes. We will describe one such program -
GYSELA, a flux-based global gyrokinetic code. Additionally, we will characterize the
difference between its flux-driven model and gradient-driven models, the evolution of
turbulent transport barriers in plasma and the ongoing research to synergize both mod-
els. We also present our results in GYSELA that describe the near-marginal conditions
that allow for turbulent transport barrier formation, demonstrate the formation of E x
B staircases and suppression of turbulence. |
