Experimental and Modeling Studies of Low-Energy Ion Sputtering for Ion Thrusters
… low-energy xenon-molybdenum (Xe+-Mo) sputtering yields for ion energies of 100 eV and less. Sputtering yield data at these energies are important for ion thruster design and lifetime prediction. The basic principles of sputtering phenomena are discussed. An overview of various popular …

Computational modeling of expanded plasma plumes in vacuum and in a tank
… contact with. Backflow contamination can lead to sputtering and effluent deposition on critical spacecraft components. A computational method for studying these interactions was developed by David Oh in 1997. He developed a Particle-in-Cell and Direct Simulation Monte Carlo (PIC-DSMC) algorithm to …

Molecular dynamic simulation of xenon bubble re-solution in uranium dioxide
… understanding of heterogeneous re-solution, sputtering and the re-solution of Xenon fission gas bubbles due to electronic energy deposition of fission fragments is investigated using MD simulations. First, a two-temperature model (TTM) coupling the electronic (e-) and phonon (p-) system is …

F-TRIDYN: A Monte-Carlo, BCA code for modeling ion-surface interactions with rough materials and coupling plasma and material codes
… role in ion irradiation processes such as sputtering; roughness can significantly increase the angle of maximum sputtering and strongly affect the sputtering yield. The complete effect of surface roughness on sputtering and other ion irradiation phenomena is not completely understood. Many …

Effects of implementation of decaborane ions in silicon
… B^+ ions of the equivalent energy and dose. The sputtering yields of Si with B in the form of decaborane clusters were measured and compared to those for boron monomer ions, estimated using an empirical formula. The surface morphology of amorphous Si, crystalline Si and Ta film irradiated with …
