Geometric numerical discretization of a quasineutral hybrid model of drift-kinetic electrons and fully kinetic ions
Nishant Narechania, Guo Meng, Emil Poulsen +1
We extend the geometric electromagnetic particle-in-cell (PIC) framework, GEMPICX, to solve the quasineutral hybrid Vlasov-Maxwell equations with drift-kinetic electrons and fully…
Suppressed Stiffness of energetic particle transport due to thermal plasma nonlinearity in tokamak plasmas
Guo Meng, Zhixin Lu, Gengxian Li
Energetic particle (EP) transport stiffness plays a crucial role in determining EP confinement in tokamak plasmas. This work investigates the impact of nonlinear thermal plasma dyn…
Gyrokinetic global simulation of Alfvenic ion temperature gradient mode in reversed magnetic shear
Gengxian Li, Zhixin Lu, Philipp Lauber +3
In this work, a systematic study of electromagnetic instabilities driven by the temperature gradient in magnetically confined fusion plasmas with reversed magnetic shear is conduct…
A quasi-neutral electromagnetic hybrid model with drift-kinetic electrons and fully kinetic ions
Guo Meng, Nishant Narechania, Eric Sonnendrücker
In this work, we propose a hybrid model that combines drift-kinetic electrons with fully kinetic ions under the quasi-neutrality assumption, discretized using a geometric particle-…
A High-order piecewise field-aligned triangular finite element method for electromagnetic gyrokinetic particle simulations of tokamak plasmas with open field lines
Zhixin Lu, Guo Meng, Eric Sonnendruecker +6
A high-order piecewise field-aligned triangular finite element method is developed and implemented for global electromagnetic gyrokinetic particle-in-cell simulations of tokamak pl…
