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…

Saturation of the kinetic ballooning instability due to the electron parallel nonlinearity
Yang Chen, Scott E. Parker
The electron parallel nonlinearity (EPN) is implemented in the gyrokinetic Particle-in-Cell turbulence code GEM [Y. Chen and S. E. Parker, J. Comp. Phys. 220, 839 (2007)]. Applicat…

A Subgrid Model for Electron-Scale Turbulent Transport in Global Ion-Scale Gyrokinetic Simulations of Tokamak Plasmas
Stefan Tirkas, Yang Chen, Scott Parker
A subgrid electron-temperature-gradient (ETG) model is demonstrated here which averages local electron-scale turbulence from the GENE code over intermediate scales in space and tim…
