Zonal Flow Excitation in Electron-Scale Tokamak Turbulence
Stefan Tirkas, Haotian Chen, Gabriele Merlo +2
The derivation of an intermediate-scale gyrokinetic-electron theory in nonuniform tokamak plasmas [Chen H. et al 2021 Nucl. Fusion 61 066017] has shown that a Navier-Stokes type no…
Predictions of improved confinement in SPARC via energetic particle turbulence stabilization
A. Di Siena, P. Rodriguez-Fernandez, N. T. Howard +8
The recent progress in high-temperature superconductor technologies has led to the design and construction of SPARC, a compact tokamak device expected to reach plasma breakeven wit…
First-principles based plasma profile predictions for optimized stellarators
A. Bañón Navarro, A. Di Siena, J. L. Velasco +6
In the present Letter, first-of-its-kind computer simulations predicting plasma profiles for modern optimized stellarators -- while self-consistently retaining neoclassical transpo…
Global gyrokinetic simulations of ASDEX Upgrade up to the transport time-scale with GENE-Tango
A. Di Siena, A. Banon Navarro, T. Luda +12
An accurate description of turbulence up to the transport time scale is essential for predicting core plasma profiles and enabling reliable calculations for designing advanced scen…
A general framework for quantifying uncertainty at scale
Ionut-Gabriel Farcas, Gabriele Merlo, Frank Jenko
In many fields of science, comprehensive and realistic computational models are available nowadays. Often, the respective numerical calculations call for the use of powerful superc…
