SteuerelektrodenGitter

SteuerelektrodenGitter, often abbreviated as SEG, refers to a control electrode grid used in vacuum tubes and other electron-based devices. Its primary function is to regulate the flow of electrons from a cathode towards an anode. The grid is typically a mesh or a series of wires placed between the cathode and the anode. By applying a voltage to the grid, the electric field in its vicinity is altered. A negative voltage on the grid repels electrons, reducing or even stopping their flow to the anode. Conversely, a positive voltage attracts electrons, increasing their flow. This control mechanism allows the SEG to act as a gate, modulating the current passing through the device. Different configurations of SEG, such as triodes (one grid), tetrodes (two grids), and pentodes (three grids), exist, each offering distinct performance characteristics and applications. These grids are crucial components in amplifiers, oscillators, and other signal processing circuits within vacuum tube technology. Their precise construction and voltage control are fundamental to the operation of these electronic devices.
