Determination of resistance against the transmission of charged particles of Rhenium-Boron (Re-B) based alloys

Abstract

In this study, the resistance of the Rhenium-Boron (Re-B) based alloys against the transmission of charged particles such as electron, proton, alpha, carbon and oxygen was investigated using the stopping power as the characterizing quantity. For this, the collision, radiative/nuclear, total stopping powers and projected range of the charged particles in the Re40-B60, Re50-B50, Re58-B42 and Re60-B40 alloys were calculated using the ESTAR, and the the Stopping and Range of Ions in Materials (SRIM) Monte Carlo code. It was found that the stopping powers of the heavy charged particles tended to decrease with increasing the rhenium concentration. These results suggest that the boron element is more suitable for heavy charged particle shielding materials compared to rhenium element.
