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…
Linear Gyrokinetic Simulations of Micro-tearing Mode: Local versus Global
Yifei Liu, Haotian Chen, Yao Yao +3
A systematic comparison of local and global linear gyrokinetic simulations of micro-tearing modes (MTMs) is performed using the GENE code. The analysis spans diverse plasma paramet…
Implicit discretization schemes for full-kinetic ion and drift-kinetic electron simulations
Zilong Li, Yang Chen, Haotian Chen +3
We present a new electromagnetic plasma simulation model with full-kinetic ions and drift-kinetic electrons. This model (termed as FIDES) solves the electric field using the implic…
On the electromagnetic effects of collisionless trapped-electron modes
Yao Yao, Haotian Chen, Yang Chen +2
We present a linear gyrokinetic theory for the electromagnetic collisionless trapped-electron mode (CTEM). It is found that the weak electromagnetic effects of CTEMs originate from…
Low-dimensional geometry learning for turbulence prediction in optimized stellarators
Xishuo Wei, Handi Huang, Haotian Chen +4
The optimized stellarator is an attractive concept for which the averaged particle radial drift is zero, and the single particle loss can be significantly reduced. But for the reac…
Discovery of Density Limit Disruption Induced by Core-localized Alfvnic Ion Temperature Gradient Instabilities in a Tokamak Plasma
Wei Chen, Liwen Hu, Jianqiang Xu +17
To achieve a high energy gain, the fusion reactor plasma must reach a very high density. However, the tokamak plasmas ofen undergo disruption when the density exceeds the Greenwald…
