Global Gyrokinetic Simulations of Electromagnetic Turbulence in STEP
Daniel Kennedy, Facundo Sheffield, Tobias Görler +6
This paper presents gradient-driven global electromagnetic gyrokinetic simulations for a conceptual burning flat-top operating point of STEP [1], STEP-EC-HD, and investigates how n…
Assessing the Impact of Alpha Particles on Thermal Confinement in JET D-T Plasmas through Global GENE-Tango Simulations
A. Di Siena, J. Garcia, R. Bilato +14
The capability of the global, electromagnetic gyrokinetic GENE code interfaced with the transport Tango solver is exploited to address the impact of fusion alpha particles (in thei…
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…
Integrated modelling and multiscale gyrokinetic validation study of ETG turbulence in a JET hybrid H-mode scenario
J Citrin, S Maeyama, C Angioni +11
Previous studies with first-principle-based integrated modelling suggested that ETG turbulence may lead to an anti-GyroBohm isotope scaling in JET high-performance hybrid H-mode sc…
New high-confinement regime with fast ions in the core of fusion plasmas
A. Di Siena, R. Bilato, T. Görler +12
The key result of the present work is the theoretical prediction and observation of the formation of a new type of transport barrier in fusion plasmas, called F-ATB (fast ion-induc…
Sensitivity-driven adaptive sparse stochastic approximations in plasma microinstability analysis
Ionut-Gabriel Farcas, Tobias Görler, Hans-Joachim Bungartz +2
Quantifying uncertainty in predictive simulations for real-world problems is of paramount importance - and far from trivial, mainly due to the large number of stochastic parameters…
