Sensitivities of electron-scale core transport in MAST Upgrade
B. S. Patel, T. Adkins, S. Blackmore +2
Integrated modelling of the Mega Ampere Spherical Tokamak Upgrade (MAST-U) indicates that turbulent electron heat transport can dominate over ion transport across a range of operat…
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…
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
This work investigates the nonlinear transition to large heat fluxes observed in local gyrokinetic simulations of electromagnetic turbulence in STEP. Using the stress-balance frame…
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…
