ABSTRACT:
A crucible contains a metal to be evaporated by heating from an electron beam source wherein the path of the electrons is controlled by a horizontal transverse magnetic field over the source and crucible. A number of small individual magnets are arranged vertically along opposite sides of the crucible parallel to the beam path. One end of each such magnet is in the closest position possible to deliver its flux lines to the magnetic field area. The magnets maybe permanent or electro- or a combination thereof. By varying the positions of the magnets, the field generated may be controlled in the desired manner.
