The device comprises an electrically conductive structure in the form of a reflector (19) disposed adjacent to the anode (3). The cathode (2) comprises a substantially rotationally symmetric, electrically conductive body (15) having a cavity (16). By configuring the cavity (16) in the body (15) of the cathode with a first, lesser depth to that boundary surface (18) of the body which is directly in front of the peripheral part of the closure of the anode (3) against the cathode, and a second, greater depth to the boundary surface (17) of the body directly in front of the central part of the closure of the anode (3) against the cathode, a device for the generation of microwaves is produced, which has higher efficiency and high peak power.

Abstract: Generating and frequency tuning of modulated high current electron beams and a specific efficient, high current, frequency-tunable device for generating intense radio frequency (RF), microwave electromagnetic fields in a rectangular waveguide. Current multiplication of a modulated seed electron beam is created by an energetic electron beam impacting a thin foil surface. The transmissive-electron-multiplier foils also mitigate both space charge expansion and improve beam propagation effects, by shorting of the radially directed electric field at the axial location of the foil(s). Foil thinness and intensity of the exit fields provide for a multiplication process occurring in a fraction of an RF period. Also included are both a self-excited microwave generator and an amplifier, using a temporally modulated laser to generate a modulated seed electron beam that is amplified. Methods to tune the oscillator are described that allow tunability over a full waveguide band.

Abstract: The invention relates to a device for producing microwave energy from an electron beam. The device includes:an electron gun (1), allowing the production of an electron beam (8) in a so-called injection zone (3);a microwave modulation circuit (7), allowing the superimposition of an alternating voltage at a given frequency on the voltage of the beam in the injection zone; the amplitude of this voltage is sufficient for ensuring, during one of its alternations, the transition between the passing state and the virtual cathode state, thus causing a modulation of the current carried by the electron beam;an output microwave circuit (4) functioning at the frequency of the modulation signal and excited by the previous modulated current.

Abstract: An electron beam device which includes a vacuum enclosure which houses an electron gun for producing an annular beam of helically rotating electrons, an iris-loaded waveguide which is supplied with high frequency power and serves to create a high frequency electromagnetic field along the axis of the beam which has a longitudinal electric field component along the beam axis, and a resonator which abstracts high frequency energy from the beam. A coil surrounds the vacuum enclosure to provide a magnetic field of increasing strength with distance downstream in the region of the iris-loaded waveguards whereby the angular velocity of the electrons in the beam is increased with little change in the axial velocity.
