Features

BS-60250DEM Electron Beam Source
  • 16kW output
    The maximum output is 16kW (1.6A at 10kV). Higher rate metal deposition is possible.
  • Large capacity crucible
    Standard crucible pocket size is 50mm in diameter.
    70 to 80mm in diameter crucible can be used with the optional pole pieces BS-60830PP250.

    *Beam movable/sweeping range is 50mm in diameter.
  • High-speed sweeping
    Beam sweeping performance has been improved compared to conventional e-beam source for metal deposition.
    Oxides such as sublimation materials can be deposited by high-speed sweeping at 500Hz or more.
  • Easy maintenance
    The top is flat structure (less vapor deposition) and the top cover is easily removable.
    Filament can be replaced without removing the copper wire of the high-voltage line.
  • Backscattered electron trap
    An optional backscattered electron trap is attachable.
    It is highly efficient for decrease of substrate temperature rise, so it is suitable for the lift-off process.
