Advances in edge and scrape-off layer diagnostics have shown that often the ion temperature is higher than the electron temperature in scrape-off layer filaments. We have therefore extended the STORM model beyond the cold ion limit commonly used, to include hot ion effects. We find that filaments are both faster and more coherent than in a cold …
Drift-reduced MHD models are widely used to study magnetised
plasma phenomena, in particular for magnetically confined fusion applications,
as well as in solar and astrophysical research. This letter discusses the choice of
Ohm’s law in these models, the resulting dispersion relations for the dynamics
parallel to the magnetic field, and the i…
