Sub-Second Collisionless Gyrokinetic Eigenvalue Solutions via Orbit-Invariant Decomposition
Anrui Luo, Jingyi Yu, Huasheng Xie +1
Fast analysis of microscopic drift-wave instabilities based on linear gyrokinetic simulations is desirable for modeling anomalous transport in fusion devices. In this work, we pres…
Minute-Scale High-Fidelity Gyrokinetic Simulations with Portability from Laptop to Supercomputer
Jian Bao, Huasheng Xie, Ming Yang +4
Global gyrokinetic particle simulations remain computationally expensive, as they demand both adequate marker statistics and three-dimensional field solvers. In this work, we prese…
VSC: A Zero-Dimensional Fusion Design Platform for Multiple Magnetic Configurations
Zekun Wang, Huasheng Xie, Feng Zhang +2
The VeloAlpha System Code (VSC) is a computational framework for zero-dimensional fusion power-balance studies across five magnetic-confinement configurations: tokamaks, magnetic m…
Cross-scale Interaction between Microturbulence and Fishbone in Fusion Plasmas
Yuehao Ma, Bin Zhang, Pengfei Liu +7
Global gyrokinetic simulations are performed for the first time to investigate cross-scale interactions between electromagnetic ion temperature gradient (ITG) turbulence and fishbo…
Electromagnetic turbulence in EAST plasmas with internal transport barrier
Yuehao Ma, Pengfei Liu, Jian Bao +2
In this study, global nonlinear electromagnetic gyrokinetic simulations are conducted to investigate turbulence in the Internal transport barrier (ITB) region of the EAST tokamak d…
Saturation of fishbone instability through zonal flows driven by energetic particle transport in tokamak plasmas
G. Brochard, C. Liu, X. Wei +17
Gyrokinetic and kinetic-MHD simulations are performed for the fishbone instability in the DIII-D discharge #178631, chosen for validation of first-principles simulations to predict…
