Title: The Role of Secondary Electron Emission in Dust Grain Charging Author: Ivana Richterová Department: Department of Surface and Plasma Science Supervisor: Prof. RNDr. Zdeněk Němeček, DrSc. Abstract: This work presents a secondary emission model focused on micron and submicron dust grains. The results allowed us to predict surface potentials of grains charged by 50 eV -- 15 keV electron beams. The probability that such electrons penetrate through grains increases with their energy and decreases with a grain size and depends on a grain shape. Model predictions were experimentally verified for glass, gold, and carbon spherical grains and for lunar regolith simulants. In dusty plasmas, charge accumulated on dust grains and plasma parameter...
