  • Electron beam line evaporator
    Patent number: 4778974
    Abstract: An electron beam line evaporator for coating heat-sensitive strips or substrates includes a magnetic trap overlying an evaporation crucible to prevent unpermissible heating and static electrification by back-scattered electrons, complemented with means to influence the injection angle of a dynamically deflected electron beam in such a manner that the beam enters the horizontal magnetic field of the trap at the same angle in each deflection phase independent of stray fields. Such means are arranged inside a gap of a pole shoe necessary for the horizontal magnetic field used by the trap and are operative to generate a vertical magnetic field variable in time and locally alongside the pole shoe.

  • Electron-beam coating of very broad strips
    Patent number: 4532888
    Abstract: Electron-beam (EB) coating of broad strips with improved film quality, and without undue scattering and deflection of the electron beam at long beam paths is accomplished with a shielding mantle, placed between the EB gun and the evaporation crucible, providing vacuum-tight shielding of the beam path from the coating chamber.
