Numerical study of the target material and geometry influence on the uranium deposition

The sputtering and reflection of uranium ions from various targets are studied by the Monte-Carlo binary collision model. A 50-1500 eV energy range and a choice of materials are dictated by the task of an efficient material collection in a plasma-based nuclear fuel regeneration machine. On the basis of modeled data analysis of the optimal collector geometry is derived. It is a cavity with a bottom tilted to walls and the aspect ratio of 2:1. Carbon was found to be the best substrate material.
