Benchmark for two-dimensional large scale coherent structures in partially magnetized ExB plasmas -- Community collaboration & lessons learned
Andrew T. Powis, Eduardo Ahedo, Alejandro Álvarez Laguna +38
Low-temperature plasmas are essential to both fundamental scientific research and critical industrial applications. As in many areas of science, numerical simulations have become a…
Rarefied xenon flow in orificed hollow cathodes
Pierre-Yves C. R. Taunay, Willca Villafana, Sangeeta P. Vinoth +2
A parametric study is conducted to quantify the effect of the keeper electrode geometry on the neutral flow quantities within orificed hollow cathodes, prior to cathode ignition. T…
Establishing Criteria for the Transition from Kinetic to Fluid Modeling in Hollow Cathode Analysis
Willca Villafana, Andrew T. Powis, Sarveshwar Sharma +2
In this study, we conduct 2D3V Particle-In-Cell simulations of hollow cathodes, encompassing both the channel and plume region, with an emphasis on plasma switch applications. The…
Numerical thermalization in 2D PIC simulations: Practical estimates for low temperature plasma simulations
Sierra Jubin, Andrew Tasman Powis, Willca Villafana +5
The process of numerical thermalization in particle-in-cell (PIC) simulations has been studied extensively. It is analogous to Coulomb collisions in real plasmas, causing particle…
Particle-in-cell modeling of electron beam generated plasma
Shahid Rauf, D. Sydorenko, S. Jubin +4
Plasmas generated using energetic electron beams are well known for their low electron temperature () and plasma potential, which makes them attractive for atomic-precision…
