Single Hearth Electron Beam Source

snglhrt2The Single Hearth Electron Beam Source is a heavy duty source offering large hearth capacity, high deposition rates, long filament life, and industrial reliability for R&D or production line applications. The source has one (1) crucible which can accept a variety of liners. The source is designed to operate at input power levels up to 12 kW. The 270 ° bent beam design permits complete shielding of the filament from evaporated materials and falling debris. The source is also equipped with a water-cooled trap and permanent magnet for greater operating efficiency and safety. The electron beam can be swept in both the X and Y axis for optimum evaporation.
