VEQDB: A Compact and Reconstructible Multi-Device Tokamak Equilibrium Database
Huasheng Xie, Ruohan Zhang, Xingyu Li +2
Tokamak equilibria are commonly exchanged as gridded G-EQDSK files whose conventions, resolutions, and machine-specific formats impede cross-device comparisons and data-driven mode…
State-Space Model-Enabled Reinforcement Learning for Magnetic Configuration Controlon EXL-50U
Pei Guo, Zhengyuan Chen, Jianguo Chen +17
Accurate feedback control of the plasma current () and centroid position is essential for the stable operation of spherical torus (ST) plasmas. Conventional propor…
Parameter Scan of Multi-Fluid Equilibria in Rotating p-11B Plasmas: Effects on Fusion Power and Bremsstrahlung Losses
Xingyu Li, Huasheng Xie, Lai Wei +1
We present VEQ-MF, a fast spectral parameter-scan framework for two-dimensional axisymmetric multi-fluid equilibria with prescribed species-dependent toroidal rotation. The solver…
First reduced model for integrated computations of helicon wave heating and current drive in magnetic fusion plasmas
Zi-Chen Kan, Lei Chang, Zhen-Yu Wang +9
Fast predictive modelling of radio-frequency heating and current drive is important for integrated tokamak scenario design, yet kinetic calculations of helicon-wave absorption rema…
VEQ: a fast parametric Grad--Shafranov solver for fixed-boundary tokamak equilibria with flexible source profiles
Ruohan Zhang, Huasheng Xie, Yueyan Li +3
Veloce EQuilibrium (VEQ) is a compact parametric framework for tokamak modeling workflows that repeatedly query continuous fixed-boundary equilibria at low latency. The VEQPy imple…
Investigation of Toroidal Rotation Effects on Spherical Torus Equilibria using the Fast Spectral Solver VEQ-R
Xingyu Li, Huasheng Xie, Lai Wei +1
Standard reduced models often fail to adequately describe the complex geometric response of tokamak plasmas to strong toroidal rotation. In this work, we present VEQ-R, a computati…
Development of a Reduced Multi-Fluid Equilibrium Model and Its Application to Proton-Boron Spherical Tokamaks
Huasheng Xie, Xingyu Li, Jiaqi Dong +8
Proton-Boron fusion requires extreme ion temperatures and robust confinement, making Spherical Tokamaks (ST) with high-power neutral beam injection primary candidates. In these dev…
A robust method for calculating plasma waves absorption in magnetized plasmas and its implementation in the BORAY ray-tracing code
Wanying Yu, Huasheng Xie, Aohua Mao +2
This paper presents a robust numerical method for calculating the total absorption rate of electromagnetic waves in magnetized plasmas, capable of determining the absorption ratio…
Screening effect of plasma flow on the resonant magnetic perturbation penetration in tokamak based on two-fluid model
Weikang Tang, Qibin Luan, Hongen Sun +5
Numerical simulation on the resonant magnetic perturbation penetration is carried out by the newly-updated initial value code MDC (MHD@Dalian Code). Based on a set of two-fluid fou…
MHD analysis on the physical designs of CFETR and HFRC
Ping Zhu, Li Li, Yu Fang +32
The China Fusion Engineering Test Reactor (CFETR) and the Huazhong Field Reversed Configuration (HFRC), currently both under intensive physical and engineering designs in China, ar…
NIMROD calculations of energetic particle driven toroidal Alfvén eigenmodes
Yawei Hou, Ping Zhu, Charlson C. Kim +4
Toroidal Alfvén eigenmodes (TAEs) are gap modes induced by the toroidicity of tokamak plasmas in absence of continuum damping. They can be excited by energetic particles (EPs) when…
