GENE-X is a global, full-f, continuum (or grid-based/Eulerian) gyrokinetic code designed to simulate plasma turbulence that governs cross-field transport in magnetic confinement fusion devices like tokamaks and stellarators. By utilizing a flux-coordinate-independent approach for the spatial discretization, the code captures both core and edge physics, modeling the transition of plasma profiles across the magnetic separatrix and into the scrape-off layer (SOL).
Predicting turbulent transport is a central challenge in fusion research, as microturbulence is the primary mechanism for anomalous heat and particle loss, directly limiting the fusion triple product and overall energy gain.
GENE-X provides a robust framework for simulating these non-linear dynamics and the resulting heat exhaust, characterizing how turbulent fluctuations drive flux across magnetic field lines toward the reactor walls. By resolving the self-consistent evolution of plasma density and temperature profiles from the core through the scrape-off layer, the code enables high-fidelity predictions of device performance and informs the optimization of magnetic configurations for future fusion power plants.
