Magnetic confinement fusion research

GVEC solves 3D magnetohydrodynamic equilibrium equations for stellarators using flexible coordinates that represent complex plasma boundaries with simple cross-sections.

Study comparing brazing and Hot Isostatic Pressing methods for bonding copper interfaces in fusion reactor divertors, evaluating thermal performance and fatigue resistance.

Simulations reveal two distinct regimes in transrelativistic shocks where competing plasma instabilities produce dramatically different particle acceleration efficiencies for ions and electrons.

gPLUTO is a GPU-optimized implementation of the PLUTO code for solving magnetohydrodynamic equations. Preliminary results demonstrate performance viability on pre-exascale parallel architectures.

Structure-preserving simulations of three magnetohydrodynamics models reveal divergent cascade mechanisms and vorticity dynamics despite shared Hamiltonian geometry.

Fully predictive gyrokinetic simulations of tokamak edge turbulence using Gkeyll validate against TCV experiments and reveal how negative triangularity enhances confinement through E×B flow shear.

Particle-in-cell simulations characterize ion-acoustic wave excitation and energy transfer mechanisms in asymmetric magnetic reconnection with cold ion populations.
