Abstract
A flat electron beam tube includes a gas-filled enclosure containing two mutually parallel front and rear plates, a control plate subdividing the enclosure and extending, parallel to the front and the rear plates, into a front chamber, a post-acceleration space, and a rear gas discharge space; the rear plate carrying a gas discharge cathode on an inner side thereof; the front plate carrying a luminescent layer excitable by electrons and a post-acceleration anode; the control plate carrying mutually parallel strip-shaped row conductors, and being formed with a number of regularly arranged electron inlet openings and mutually parallel, strip-shaped column conductors, and being formed with a number of regularly arranged electron outlet openings, the column conductors being disposed crosswise to the row conductors, and the electron outlet openings being associated, respectively, by means of cutouts formed in the control plate, with given electron inlet openings; the row conductors being connected successively to a potential more positive than the potential of the gas discharge cathode so that an electron-supplying gas discharge burns between the opposite gas discharge cathode and the connected row conductor; mutually associated electron inlet openings and electron outlet openings being disposed in non-overlapping relationship in a direction perpendicular to the plane of the front and the rear plates; and the column conductors being always at a potential more negative than that of the row conductor being then connected.
