Interaction of low-energy protons with aluminum surface

Abstract

The article presents the results of researches on the protons interaction with energy of 260 eV with a surface of aluminum foil at the temperature of 300 °C, ion current density of ~ 1.5 mA/cm2 with an exposure of 11 hours. The surface is covered with bubbles and microcracks. There is a phenomenon of surface blistering. The substantial cleaning of the surface from oxides occurs due to sputtering of the surface, as well as because of their repair in hydrogen plasma. The hydrogen content substantially increases at the depth of the sample after irradiation of aluminum with protons. The sputtering plasma-chemical reactor materials is observed.
