WebThe control grid is wound from stiff, fine wire (often tungsten) as a helix around the cathode, and it is most effective close to the cathode surface, where the velocity of the electrons is less, than near the anode, by which time the electrons have acquired considerable momentum and are not so easily repelled. WebSchematic symbol used in circuit diagrams for a vacuum tube, showing control grid. The control grid is an electrode used in amplifying thermionic valves (vacuum tubes) such as the triode, tetrode and pentode, used to control the flow of electrons from the cathode to the anode (plate) electrode. The control grid usually consists of a cylindrical screen or helix …

The control grid usually consists of a cylindrical screen or helix of fine wire surrounding … See more In a valve, the hot cathode emits negatively charged electrons, which are attracted to and captured by the anode, which is given a positive voltage by a power supply. The control grid between the cathode and … See more The grid in the first triode valve consisted of a zig-zag piece of wire placed between the filament and the anode. This quickly evolved into a helix or cylindrical screen of fine wire placed between a single strand filament (or later, a cylindrical cathode) and a cylindrical … See more A variation of the control grid is to produce the helix with a variable pitch. This gives the resultant valve a distinct non-linear characteristic. This is often exploited in R.F. amplifiers … See more By placing the control grid closer to the filament/cathode relative to the anode, a greater amplification results. This degree of amplification is … See more A valve can contain more than one control grid.
