Abstract: An ion source in which ions of normally solid materials are easily produced. A plasma is generated in a gas adjacent the solid material from which ions are to be produced. The solid is negatively charged and the gas plasma ions bombard the solid, sputtering off ions of the solid. This is accomplished through the use of a Penning discharge with a cold cathode-type source and a centrally positioned and negatively charged dynode upon which the solid material is mounted, the dynode being electrically connected to the cathode and provided with an exit slit through which the metallic ions are extracted from plasma potential.

Abstract: A high energy discharge apparatus uses a generally electron transparent thin foil anode of various configuration which is arranged parallel to and spaced apart between a pair of cathodes, and energized to create a potential difference between the anodes and cathodes causing electrons to be reflected back and forth through the foil anode with the concurrent discharge of ions being accelerated to the cathode.

Abstract: Apparatus for ionizing gases at very low pressures comprising inner and outer electrodes wherein the inner electrode is substantially circular in cross section and the outer electrode surrounding the inner electrode may be other than a figure of revolution or may be eccentrically positioned with respect to the inner electrode which inner electrode is less in length than two times the length of the surrounding outer electrode and is spaced therefrom a distance which is greater than the diameter of the inner electrode for a distance of not less than two-thirds the length of the surrounding outer electrode.
