Ion Generators

"Kaufman thrusters," or electron bombardment thrusters, were developed for a spacecraft electric propulsion technique called ion propulsion. The technique, conceived by a Lewis Research Center engineer, is used by industry to etch microcircuits for electronic systems and deposition of thin films as coatings on gas atoms to create ions in a discharge chamber. The ions are ejected from the chamber as ion beams, then mixed with an equal number of electrons becoming a thrusting force. Commonwealth Scientific Corporation's product line derives largely from Dr. Kaufman's technology and includes ion sources for a number of applications.
