Towards fully predictive gyrokinetic full-f simulations: validation and triangularity studies in TCV
A. C. D. Hoffmann, T. N. Bernard, M. Francisquez +6
Designing economical magnetic confinement fusion power plants motivates computational tools that can estimate plasma behavior from engineering parameters without direct reliance on…
Axisymmetric Gyrokinetic Simulation of ASDEX-Upgrade Scrape-off Layer Using a Conservative Implicit BGK Collision Operator
D. Liu, J. Juno, G. W. Hammett +3
Collisions play an important role in turbulence and transport of fusion plasmas. For kinetic simulations, as the collisionality increases in the domain of interest, the size of the…
Effects of oxidation and impurities in lithium surfaces on the emitting wall plasma sheath
Kolter Bradshaw, Ammar Hakim, Bhuvana Srinivasan
Use of lithium as a surface coating in fusion devices improves plasma performance, but the change in wall properties affects the secondary electron emission properties of the mater…
Direct Comparison of Gyrokinetic and Fluid Scrape-Off Layer Simulations
A. Shukla, J. Roeltgen, M. Kotschenreuther +7
Typically, fluid simulations are used for tokamak divertor design. However, fluid models are only valid if the SOL is highly collisional, an assumption that is valid in many presen…
