    Abstract: An electron beam generator which can operate in pulse or continuous mode, has an electron beam which is emitted in a main electron gun including a thermionic cathode and an anode. Used in association with this main electron gun is an auxiliary electron gun including a cathode, a grid intended to modulate an auxiliary electron beam in pulses when it is operating in pulse mode or to adjust the current of the auxiliary electron beam when it is operating in continuous mode, and an anode. The anode is in thermal and electric contact with the cathode of the main electron gun. The auxiliary electron beam controls the emission from the cathode. The electron beam emitted by the main electron gun is not disturbed by crossing the grid. Application of the electron beam generator is notably to microwave longitudinal interaction tubes operating at high average and/or peak power.

    Abstract: Apparatus is disclosed for generating high density pulses of electrons thermionically. The apparatus includes a metallic target maintained within a low pressure cesium vapor atmosphere. A laser rapidly heats the cesiated target surface to a high temperature in a time short compared with the residence time of cesium atoms adsorbed on the target surface. This rapid surface heating in combination with the adsorbed cesium atoms emits copious quantities of electrons forming a high current density pulse.

    Abstract: PROBLEM TO BE SOLVED: To provide an electron gun with little individual difference due to variation in manufacture, and with good electron emission property.
    SOLUTION: An electron gun is provided with a cathode pellet discharging electrons, a heater cap integrating a heater imparting heat energy for discharging electrons to the cathode pellet, a Wehnelt electrode for focusing an electron beam in which the average angle of a surface against the outermost shell of the electron beam is formed to be a shape matching a pierced angle, and a retainer installing and fixing the cathode pellet on the heater cap by restraining the periphery edge of the cathode pellet to the heater cap and a part covering the periphery edge of an electron discharging surface of the cathode pellet works as a part of the Wehnelt electrode.
