Streamline integration as a method for structured grid generation in X-point geometry
M. Wiesenberger, M. Held, L. Einkemmer +1
We investigate structured grids aligned to the contours of a two-dimensional flux-function with an X-point (saddle point). Our theoretical analysis finds that orthogonal grids exis…
GREENY: A Full-F 2D Gyrofluid Reconnection Code
F. F. Locker, M. Held, T. Stocker-Waldhuber +3
We present the 2D gyrofluid magnetic reconnection code GREENY (Gyrofluid Reconnection with Extended Electromagnetic Nonlinearity). After a brief introduction to gyrofluids, magneti…
Effects of plasma resistivity in three-dimensional full-F gyro-fluid turbulence simulations
M. Wiesenberger, M. Held
A full-F, isothermal, electromagnetic, gyro-fluid model is used to simulate plasma turbulence in a COMPASS-sized, diverted tokamak. A parameter scan covering three orders of magnit…
Dielectric Coatings for IACT Mirrors
A. Förster, T. Arrmstrong, P. Chadwick +1
Imaging Atmospheric Cherenkov Telescopes for very-high energy gamma-ray astronomy need mirror with high reflectance roughly in the wavelength between 300 and 550 nm. The current st…
Gyrofluid Magnetic Reconnection Beyond the δ F Approximation
F. F. Locker, M. Rinner, M. Held +1
Magnetic reconnection in a two-dimensional system is studied employing a novel Full-F gyrofluid model with arbitrary- wavelength polarization. In strongly magnetized plasmas, the l…
Lattice Boltzmann model for collisionless electrostatic drift wave turbulence obeying Charney-Hasegawa-Mima dynamics
M. Held, A. Kendl
A lattice Boltzmann method (LBM) approach to the Charney-Hasegawa-Mima (CHM) model for adiabatic drift wave turbulence in magnetised plasmas, is implemented. The CHM-LBM model cont…
