  • Patent number: 3969628
    Abstract: Energetic electron beam assisted x-ray generator having a plasma generator nd an electron source interconnected by a sealed pinch tube and control means for the plasma generator, electron source, and said sealed pinch tube to cause the electron source to be focused on the plasma from the plasma generator and to cause the electron source to be transmitted to the plasma of the plasma generator at the appropriate time to cause a maximum amount of soft x-rays to be produced by the interaction of the outputs of the plasma generator and the electron source when said plasma has been seeded with appropriate high Z-material.
    Type: Grant
    Filed: April 4, 1974
    Date of Patent: July 13, 1976
    Assignee: The United States of America as represented by the Secretary of the Army
    Inventors: Thomas G. Roberts, Romas A. Shatas, Harry C. Meyer, III, John D. Stettler
  • Patent number: 3968378
    Abstract: An electron beam driven neutron generator which comprises an electron sou connected to a beam forming and guiding section for guiding the electron beam to a target which is held by a portion of the beam forming and guiding section and in which the target has a magnetic field thereabout to control heat conduction by charged particles at the target to cause neutrons to be produced at the target by interaction of the output from the electron beam source and the material forming the target.
    Type: Grant
    Filed: July 11, 1974
    Date of Patent: July 6, 1976
    Assignee: The United States of America as represented by the Secretary of the Army
    Inventors: Thomas G. Roberts, Romas A. Shatas, John D. Stettler
  • Patent number: 3967582
    Abstract: A mechanism for the protection of optical glass plates against high energy laser radiation effects. The mechanism includes a water coated or water impregnated film positioned in a manner to shield the optical plates and absorb radiation from an attacking high energy laser source. An automatic means is provided for advancing the film when it experiences a rapid rise in temperature.

    Inventors: Thomas G. Roberts, Thomas A. Barr, Jr.
  • Patent number: 3959659
    Abstract: Energetic electron beam assisted fusion neutron generator which comprises a lasma generator and an electron source interconnected by a pinch tube and control means for the plasma generator, electron source, and said pinch tube to cause the electron source to be focused on the plasma from the plasma generator and to cause the electron source to be transmitted to the plasma of the plasma generator at the appropriate time to cause a maximum amount of neutrons to be produced by the interaction of the outputs of the plasma generator and the electron source through an appropriate gas filling the plasma generator.
    Type: Grant

    Date of Patent: May 25, 1976
    Assignee: The United States of America as represented by the Secretary of the Army
    Inventors: Thomas G. Roberts, Romas A. Shatas, Harry C. Meyer, III, John D. Stettler
  • Patent number: 3946240
    Abstract: An energetic electron beam fusion neutron generator in which a plasma is duced by a plasma generator to produce neutrons and to increase the number of neutrons produced, an electron source is guided to the produced plasma to further heat the plasma and produce an even greater number of neutrons. The inner electrode of the plasma generator utilizes the inneraction of the beams self magnetic field with the inner surface of the inner electrode to guide the electron source to the plasma.
