The results of investigations of the interaction of protons with energy of 250…260 eV with the surface of tungsten foil are presented. Sputtering of tungsten occurs at a rate of ~ 0.5 μm/h at a temperature of 300°C and an ion current density of 1.5 mA/cm² . The surface of tungsten significantly ch...
