Title

Fully-Kinetic Pife-Pic Simulations of Plasma Charging at Lunar Craters

Abstract

This paper presents a fully-kinetic numerical investigation of plasma charging at lunar craters using the most recently developed Parallel Immersed-Finite-Element Particle-in-Cell (PIFE-PIC) code. This model explicitly 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. 3-D domain decomposition is used for both particle-push and field-solve steps of the PIC loop to distribute the computation among multiple processors. Simulations are presented to study surface charging and lunar habitat charging near the lunar craters.
