High-order stochastic integration schemes for the Rosenbluth-Trubnikov collision operator in particle simulations
Zhixin Lu, Guo Meng, Tomasz Tyranowski +1
In this study, we consider a numerical implementation of the nonlinear Rosenbluth-Trubnikov collision operator for particle simulations in plasma physics in the framework of the fi…

Global scaling of the heat transport in fusion plasmas
Sara Moradi, Johan Anderson, Michele Romanelli +2
A global heat flux model based on a fractional derivative of plasma pressure is proposed for the heat transport in fusion plasmas. The degree of the fractional derivative of the he…

Gyrokinetic analysis and simulation of pedestals, to identify the culprits for energy losses using fingerprints
M. Kotschenreuther, X. Liu, D. R. Hatch +14
Fusion performance in tokamaks hinges critically on the efficacy of the Edge Transport Barrier (ETB) at suppressing energy losses. The new concept of fingerprints is introduced to…
