Rotating field electron beam apparatus and method

Image Number 7 for United States Patent #4763005.

An improved method and apparatus for bombarding an object with charged particles. A shaping magnet is provided to spread the beam of charged particles emitted by a charged particle gun after the beam has left the gun. The beam is shaped so that it will completely envelope the object and provide substantially uniform penetration. The shaping of the electron beam is done after the beam has left the electron gun, unlike the prior art devices which shape the beam in the gun to produce a focusing effect. This provides more control over the shape of the beam.
