On the transition to large fluxes and access to second stability in gyrokinetic simulations of electromagnetic turbulence in STEP
Daniel Kennedy, Yujia Zhang, Toby Adkins +6
The paper investigates why large heat fluxes appear in gyrokinetic simulations of electromagnetic turbulence in the STEP tokamak, identifying a critical q²βₑ threshold that trigger…
