Fully-Kinetic Pife-Pic Simulations of Photoelectron Sheaths and Plasma Charging at Lunar Craters
Abstract
This paper presents a fully-kinetic numerical investigation of photoelectron sheaths and plasma charging at lunar craters using the Parallel Immersed-Finite-Element Particle-in-Cell (PIFE-PIC) code. This model includes the lunar regolith layer and the bedrock in the simulation domain, taking into account the regolith layer thickness and permittivity, and is capable of resolving a non-trivial surface terrain or spacecraft configuration. Simulations are presented to study surface charging and lunar lander charging as well as photoelectron sheaths near the lunar craters at the terminator region.
