WebA CRT is an electronic tube designed to display electrical data. The basic CRT consists of four major components. Electron Gun Focussing & Accelerating Anodes Horizontal & Vertical Deflection Plates Evacuated Glass Envelope 1. Electron Gun It is used for producing a strain of electrons 2. Focussing & Accelerating Anodes WebThe main purpose of the first (FOCUSING) anode is to focus the electrons into a narrow beam on the screen. The second (ACCELERATING) anode accelerates the electrons as they pass. The control grid is cylindrical and has a small opening in a baffle at one end.
