Title

Kinetic Particle Simulations of Plasma Charging and Dust Transport Near Uneven Lunar Surface Terrain

Abstract

This paper presents a kinetic particle simulation study of the plasma charging and dust transport near the uneven lunar surface terrain. A fully-kinetic 3-D finite-difference (FD) particle-in-cell (PIC) code is utilized to simulate the plasma interaction with uneven surface terrain. The levitation and transport of charged dust grains under the effect of the local photoelectron sheath will be investigated. The profile of quantities of interests, such as electric potential, electric field, solar wind and photoelectron density, and the concentration of charged dust within the photoelectron sheath will be presented.
