    摘要： A high-power switch tube (10) is shown constructed from a plurality of electron guns each having a cathode (12) and an anode (32). Between the cathode and anode is mounted a shadow grid (22) closest to the cathode beyond which is mounted a control grid (26), a screen grid (28), and, in some applications, a suppressor grid (30). Each anode (32) is formed with an anode cavity (34) having an opening (36) that is smaller in dimension than the largest dimension of the cavity, thus forming a Faraday cage collector which prevents secondary emission problems.

    摘要： An additively manufactured apparatus having a gas filled sealed cavity (1490) containing at least two additively manufactured cathodes (1458, 1486, 1488) and an additively manufactured anode (1460, 1462, 1468, 1470) spaced from the cathodes such that a continuous electric discharge of the gas stimulated between at least one of the cathodes (1458, 1486, 1488) and the anode (1460, 1462, 1468, 1470) provides a Boolean function output at the anode corresponding to electrical input signals at two of the cathodes.

    摘要： A vacuum tube has a housing with magnetic elements disposed adjacent to the housing, and the housing forms a vacuum space therein. A cathode and an anode are installed inside the housing. When an external power is supplied to the cathode and the anode, free electrons are generated in the housing. The magnetic elements may be permanent magnets made as fractions of the housing. The magnetic elements generates a magnetic field, and forms a three dimensional magnetic barrier in the housing. The barrier traps the electrons inside, and prevents the electrons from contacting the cathode and an anode as well as the housing or other internal elements of the vacuum tube. Accumulation of the electrons in the housing is achieved and may be utilized for various industrial applications.

    摘要： The present invention relates to a bidirectional high-voltage cold-cathode field-emission vacuum electron tube, comprising:
    a) a cylindrical inner electrode encircled by a first cylindrical grid, in turn encircled by a second cylindrical grid, in turn encircled by a cylindrical outer electrode; the inner and outer electrodes and the first and second grids sharing a common main axis;
    b) the inner and outer cylindrical electrodes respectively functioning bidirectionally, as either a field emission cathode or an anode, depending on the instantaneous polarity of the signal applied across said electrodes;
    c) the radial spacing from the inner electrode to the first grid is such as to create therebetween a circular waveguide supporting the transverse electromagnetic mode; and the spacing between the second grid and the outer electrode is such as to create therebetween a circular waveguide supporting the transverse electromagnetic mode; and
    d) the radial spacing between the first grid and the second grid is sufficient to prevent flashover between the first and second grids at an intended operating voltage.

    摘要： The Venetian blind dynode (5A) and metal channel dynodes (5B) of a dynode section (5), together with insulation spacers (insulation plates) (11), are fitted on pillars (9) erected on a stem plate (3) constituting a vacuum vessel, in which state the Venetian blind dynode (5A), metal channel dynodes (5B) and insulation spaces (insulation plates) (11) are integrally firmly supported by the pillars (9); therefore, the Venetian blind dynode (5A), metal channel dynodes (5B) and insulation spaces (insulation plates) (11) have no possibility of causing accidental lateral deviation due to vibration or shock, thus ensuring that the dynode section (5) develops excellent vibration resistance performance.
