Dynamics of rapidly spinning blob-filaments: fluid theory with a parallel kinetic extension
J. R. Myra, J. Cheng, S. E. Parker
Blob-filaments (or simply 'blobs') are coherent structures formed by turbulence and sustained by nonlinear processes in the edge and scrape-off layer (SOL) of tokamaks and other ma…
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…
Comparison of edge turbulence characteristics between DIII-D and C-Mod simulations with XGC1
I. Keramidas Charidakos, J. R. Myra, S. Ku +4
The physical processes taking place at the edge region are crucial for the operation of tokamaks as they govern the interaction of hot plasma with the vessel walls. Numerical model…
Analysis of equilibrium and turbulent fluxes across the separatrix in a gyrokinetic simulation
I. Keramidas Charidakos, J. R. Myra, S. Parker +4
The SOL width is a parameter of paramount importance in modern tokamaks as it controls the power density deposited at the divertor plates, critical for plasma-facing material survi…
