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…
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…
A kinetic CMA diagram
Zilong Li, Haotian Chen, Zhe Gao +1
We present a kinetic Clemmow-Mullaly-Allis (CMA) diagram by systematically analysing the kinetic effects on the wave propagation in a homogeneous thermal plasma. The differences be…
Linear gyrokinetic simulation of kinetic infernal mode
Gengxian Li, Haotian Chen, Yong Xiao
Kinetic infernal mode (KIM) is an electromagnetic instability driven by thermal ions in weak magnetic shear region with a frequency similar to the kinetic ballooning mode (KBM). Gy…
