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…
Omnigenous stellarator equilibria with enhanced stability
Rahul Gaur, Rory Conlin, David Dickinson +7
To build an economically viable stellarator, it is essential to find a configuration that satisfies a set of favorable properties to achieve efficient steady-state nuclear fusion.…
On the importance of parallel magnetic-field fluctuations for electromagnetic instabilities in STEP
D. Kennedy, C. M. Roach, M. Giacomin +8
[ABRIDGED] This paper discusses the importance of parallel perturbations of the magnetic-field in gyrokinetic simulations of electromagnetic instabilities and turbulence at mid-rad…
Nonlinear microtearing modes in MAST and their stochastic layer formation
M. Giacomin, D. Dickinson, D. Kennedy +2
First nonlinear gyrokinetic simulations of microtearing modes in the core of a MAST case are performed on two surfaces of the high-collisionality discharge used in Valovič et al. N…
New linear stability parameter to describe low- electromagnetic microinstabilities driven by passing electrons in axisymmetric toroidal geometry
M. R. Hardman, F. I. Parra, B. S. Patel +8
In magnetic confinement fusion devices, the ratio of the plasma pressure to the magnetic field energy, , can become sufficiently large that electromagnetic microinstabilities be…
