Physics of Plasmas, Volume 30, Issue 4, April 2023. Coronal mass ejections (CMEs) are some of the most energetic and violent events in our solar system. The prediction and understanding of CMEs are of particular importance due to the impact that they c…
Physics of Plasmas, Volume 30, Issue 4, April 2023. We present methods and algorithms that allow the Vlasiator code to run global, three-dimensional hybrid-Vlasov simulations of Earth’s entire magnetosphere. The key ingredients that make Vlasov simulat…
Physics of Plasmas, Volume 30, Issue 4, April 2023. This paper considers the instabilities of imploding aluminum metal-puff Z-pinches with an outer plasma shell. An experiment was performed on the GIT-12 generator (3.2–3.6 MA, ∼1 μs implosion times, an…
Physics of Plasmas, Volume 30, Issue 4, April 2023. Losses of beam ions due to Alfvén modes are simulated for discharges in the Large Helical Device at Toki, Japan, using a guiding center code. High frequency beam particle resonances are found for the …
Physics of Plasmas, Volume 30, Issue 4, April 2023. Investigation of linear gyrokinetic ion-scale modes ([math]) finds that a transition from ion temperature gradient to microtearing mode (MTM) dominance occurs as the density is increased near the pede…
Physics of Plasmas, Volume 30, Issue 4, April 2023. We present a robust optimization algorithm for the design of electromagnetic coils that generate vacuum magnetic fields with nested flux surfaces and precise quasi-symmetry. The method is based on a b…
