    摘要： A klystron has a hollow beam electron gun that has a circular planar electron emitting surface. A hollow electron beam is directed from the electron gun through a plurality of drift tubes, resonant chambers and magnetic fields to a collector. The hollow electron beam does not experience significant radial movement and can operate at a lower beam voltage which reduces the required length of the RF interaction circuit and lowers the risks of RF arcing.

    摘要： An exemplary system and method for providing a multi-layer klystron-type electron beam device for the generation and amplification of millimeter-wave electromagnetic radiation is disclosed as comprising inter alia: a cathode layer (130); a collector layer (100); an extraction layer (120); a control layer (140); an input cavity (150); an output cavity (170); several ceramic spacer layers (103, 105, 107) dispose intermediately between the cathode (130) and the collector (100); and optionally, several magnetic ceramic layers (160, 165) for beam forming and focusing. After the klystron's layers are assembled, the device may be fired to form a substantially monolithic structure.

    摘要： A reflex triode for use in producing ultra-high-current (>10.sup.5 A), ul-high-power (>10.sup.11 W) ion beams includes an improved anode and an improved cathode and has a low inductance design. A cylindrical anode stalk supporting the anode is positioned inside of and closely spaced from a cylindrical cathode shank which supports the cathode. Magnetic insulation allows for a close spacing between the anode stalk and cathode shank which reduces the inductance. The improved cathode is embedded in a cathode mount to reduce divergence of the ion beam. The improved anode consists of conducting concentric rings with thin film in the space between the rings to produce a more uniformly dense ion beam having low divergence.
