Quick Summary

A suppressor grid is a component within an electron tube, specifically positioned between the screen grid and the plate (or anode). Its primary function is to prevent secondary electrons from moving between these two electrodes.12

In an electron tube, a grid is an electrode designed to control the flow of electrons or ions. While a control grid regulates current between the cathode and anode, a screen grid, often at a fixed potential, reduces the anode's electrostatic effect on the control grid. The suppressor grid plays a crucial role in maintaining the tube's performance by managing secondary electron flow.21
