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…

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…
