  • Electron beam tube output arrangement
    Patent number: 7218053
    Abstract: An electron beam tube of the type for amplification of RF signals comprising an electron gun, an interaction region within a vacuum, an RF input and an RF output arrangement, the RF output arrangement comprising an output coaxial line and a coaxial divider, wherein the coaxial divider is arranged to divide a signal on the coaxial line into a plurality of signals and wherein the vacuum within the interaction region extends into the coaxial divider.
    Type: Grant

  • Electron beam tubes
    Patent number: 6465958
    Abstract: An electron beam tube such as a klystron includes a penultimate resonant cavity (22) located before the output cavity (14). The penultimate resonant cavity (22) is arranged to be inductively coupled, being resonant at a frequency which is slightly greater than a harmonic frequency. This provides increased sharpening of bunches of electrons arriving at the output cavity (14) giving increased efficiency at the output.
