  • 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.

  • Electron beam strip-coating apparatus
    Patent number: 4524717
    Abstract: The present invention is a coating apparatus for temperature-sensitive broad strips or similar substrates. To obtain a high quality of coating, it is necessary to minimize the path of the electron beam (EB) through the vapor cloud, and to keep away backscattered electrons from the evaporating material. According to the invention, this problem is solved by assembling a sector field with a vertical field direction at the deflection system connected with the EB gun, which is followed by a deflection field with a horizontal field direction. The divergent electron beam is guided in lines to the evaporating material by the geometry of the fields.
