The electron gun generates the beam of electrons; these electron beam consists of several electrons moving towards phosphor screen. The control grids are used to control the intensity of electrons.
The accelerating anodes are used to increase the velocity of electrons so that they strike the phosphor screen with high speed and thus forms a bright spot. The beam creates the luminous spot at the different points on the screen. This becomes easy with the help of deflection plates which deflects the electron beam through various angles.
