AI-Accelerated Gyrokinetic Predictions of Turbulent Transport for Stellarator Design Optimization and Experimental Planning
R. Michael Churchill, Matt Landreman, Jong Youl Choi +10
Previous work built AI-based surrogates for a nonlinear gyrokinetic simulation code with the goal of using them for fast, direct calculations of turbulent ion heat flux in stellara…
Unraveling Diffusion in Fusion Plasma: A Case Study of In Situ Processing and Particle Sorting
Junmin Gu, Paul Lin, Kesheng Wu +6
This work starts an in situ processing capability to study a certain diffusion process in magnetic confinement fusion. This diffusion process involves plasma particles that are lik…
Simplicial Approximation of Deforming 3D Spaces for Visualizing Fusion Plasma Simulation Data
Congrong Ren, Hanqi Guo
We introduce a fast and invertible approximation for data simulated as 2D planar meshes with connectivities along the poloidal dimension in deforming 3D toroidal (donut-like) space…
Electromagnetic total-f algorithm for gyrokinetic particle-in-cell simulations of boundary plasma in XGC
Robert Hager, Seung-Hoe Ku, A. Y. Sharma +2
The simplified delta-f mixed-variable/pull-back electromagnetic simulation algorithm implemented in XGC for core plasma simulations by M. Cole et al. [Phys. Plasmas 28, 034501 (202…
Total Fluid Pressure Imbalance in the Scrape-Off Layer of Tokamak Plasmas
R. M. Churchill, J. M. Canik, C. S. Chang +5
Simulations using the fully kinetic neoclassical code XGCa were undertaken to explore the impact of kinetic effects on scrape-off layer (SOL) physics in DIII-D H-mode plasmas. XGCa…
