A coherent structure transport model for scrape-off layer turbulence
Zhichen Feng, James Myra, Junyi Cheng +5
Understanding the locality of high-temperature plasma energy deposition on material surfaces in fusion reactors is critical for design. Here, we utilize the Gyrokinetic ElectroMagn…
Global simulations of kinetic-magnetohydrodynamic processes with energetic electrons in tokamak plasmas
Jian Bao, Wenlu Zhang, Ding Li +7
The energetic electrons (EEs) generated through auxiliary heating have been found to destabilize various Alfven eigenmodes (AEs) in recent experiments, which in turn lead to the EE…
MAS: A versatile Landau-fluid eigenvalue code for plasma stability analysis in general geometry
Jian Bao, Wenlu Zhang, Ding Li +8
We have developed a new global eigenvalue code, Multiscale Analysis for plasma Stabilities (MAS), for studying plasma problems with wave toroidal mode number n and frequency omega…
Transport Barrier and Spinning Blob Dynamics in the Tokamak Edge
Junyi Cheng, James Myra, Seung-Hoe Ku +3
In this work, we investigate the dynamics of plasma blobs in the edge of magnetic confinement devices using a full-f gyrokinetic particle-in-cell code with X-point geometry. In sim…
A New Paradigm for Fast and Repetitive Chirping of Alfvén Eigenmodes
Junyi Cheng, Wenlu Zhang, Zhihong Lin +4
A novel 2D nonlinear dynamical paradigm is constructed to interpret the fast and repetitive frequency chirping and amplitude oscillation of Alfvén eigenmodes excited by energetic p…
