FIELD: electronic engineering; means for amplifying television signals in ultrahigh frequency band. ^ SUBSTANCE: device anode has diaphragm incorporating holes for electron flux transit. Anode tube accommodates perforated conducting component electrically connected to disk-shaped conducting holder of grid by means of additional conducting components passed in a spaced relation through anode diaphragm holes. In this way electrostatically single-potential lens is produced within anode tube affording passage of electron flow dispensing with focusing magnetic field. Such design provides for eliminating adverse impact of magnetic field nonuniformity on current flow. ^ EFFECT: reduced accelerating voltage. ^ 21 cl, 7 dwg |
