Experimental Investigation of Technology for Relief Electron-Beam Modification of a Tungsten Surface

In this study, the possibility of using Surfi-Sculpt technology for relief modification of the tungsten surface on a technological electron-beam equipment with an accelerating voltage of 60 kV and an electron gun of the ELA-60 type is investigated. The electron beam power density sufficient for intense evaporation of tungsten and obtaining a relief surface is determined. The dynamics of the surface relief growth rate is analyzed using a six-point star scanning as a function of the electron beam velocity and direction.
