The electron gun is responsible for producing a fine beam of highly accelerated electrons that can be focused on the screen.
The function of an electron gun
The main function of the electron gun is to produce and accelerate the beam of an electron inside the vacuum tube of the CRT. Generating and accelerating the gun requires the heater, cathode electrodes, grid, and different types of anodes.
- It is a device used in a cathode ray tube for displaying the image on the phosphorous screen of CRT.
- The electron gun emits electrons and forms them into a beam with the help of a heater, cathode, grid, pre-accelerating, accelerating and focusing anode.
