Abstract: A radio-frequency amplifier includes at least two double-ended electron discharge devices in coaxial-type, radio-frequency cavity-resonator circuits. Each discharge device has a discharge region so that the amplifier comprises a plurality of longitudinally spaced-apart, electrically connected discharge regions. Each of the discharge regions has a cathode with an anode circumscribing the cathode. At least one grid electrode is disposed between the cathode and the anode. A coaxial input transmission line is loop-coupled to an input cavity-resonator circuit and a coaxial output transmission line is loop-coupled to an output cavity-resonator circuit.

Abstract: A klystron oscillator has an input cavity resonant in a TM.sub.010 mode and a larger output cavity resonant in a TM.sub.OnO mode where n is an integer greater than 1, preferably equal to 2. The input cavity, with re-entrant bosses defining a buncher gap, projects into the output cavity to form one of two re-entrant bosses thereof defining a catcher gap.

Abstract: A standing-wave linear charged particle accelerator is disclosed which comprises a plurality of interlaced substructures, with each substructure having a plurality of accelerating cavities disposed along the particle beam path and having side cavities disposed away from the beam path for electromagnetically coupling the accelerating cavities. A radio-frequency electromagnetic standing wave is supported in each substructure, with the wave in each substructure being phased with respect to the wave in every other substructure so that the particle beam will experience a maximum energy gain throughout its path through the accelerator. A slotted input coupler is connected to the accelerator to individually drive each of the substructures.

Abstract: A klystron tube is provided with a long drift tube between the last prebuncher interaction gap and the first buncher interaction gap. The length of the long drift tube is such that in a preferred embodiment the ratio of the peak R.F. gap voltage to the D.C. beam voltage is between 1.4 .times. Wq/w and 2Wq/w where Wq is the reduced plasma frequency in radians per second and w = 2.pi. .times. signal frequency. By this means the distribution of the electrons in the beam is improved.

Abstract: A continuously tunable multicavity klystron and gang tuning apparatus therefor includes a separate tuning element in association with each klystron cavity resonator for setting the respective cavity resonant frequencies. A carriage which is translated in a generally straight line path in response to the rotation of a single tuning shaft carries a plurality of elongated deformable metal bands. These bands are variable pitch cams that are followed by cam followers coupled to the tuning elements for each of cavity resonators. Each deformable band is supported on the carriage at several discrete points along the band length, and adjustment screws are provided for setting the band height and consequent tuning element contour. Such adjustment compensates for the nonlinear tuning characteristic of the cavity resonators in order to thereby obtain a resultant substantially linear cavity resonant frequency versus tuning shaft rotation characteristic. Because of the deformable nature of the bands, a smooth and continuous cam surface is formed between these discrete points.
