  • System and method for producing terahertz radiation
    Patent number: 7473914
    Abstract: An apparatus for producing an annular electron beam comprises a cathode for generating electrons, a cavity having an annular shape and operable to receive the electrons, an energy input coupled to the cavity, where the energy input is operable to supply Radio Frequency (RF) energy at the cavity and an energy output coupled to the cavity and operable to receive accelerated electrons from the cavity and operable to output the accelerated electrons as an annular electron beam.
    Type: Grant

    Date of Patent: January 6, 2009
    Assignee: Advanced Energy Systems, Inc.
    Inventors: Alan M. Todd, Hans Peter Bluem, Robert Henry Jackson, Jr.
  • Axisymmetric emittance-compensated electron gun
    Patent number: 7116064
    Abstract: An electron gun includes a cathode, a cavity, and an energy input. The cavity resonates at a particular frequency, and the cathode generates an electron beam along its longitudinal axis when driven by resonant electromagnetic radiation of the particular frequency. The energy input introduces electromagnetic radiation of the particular frequency into the cavity along the longitudinal axis of the cathode.
