Control

Since electrons are charged particles, their direction of travel can be controlled by electromagnetic fields. When the accelerated beam of electrons emerge from the aperture in the anode, it begins to diverge because of mutual repulsion. An electromagnetic coil is used to re-focus the beam of electrons, allowing the beam to be focused at any location beyond the plane of the focus coil. Deflection coils can be added to manipulate the beam to move in predetermined patterns. These parameters can be adjusted to optimize process stability and to accommodate joint fit-up, shrinkage, or cosmetic appearance.
