The cathode ray Tube (CRT) is the heart of the C.R.O. the CRT generates the electron beam, accelerates the beam, deflects the beam and also has a screen where beam becomes visible as a spot. The main parts of the CRT are:
1.Β Β Β Β Electron Gun
2.Β Β Β Β Deflection system
3.Β Β Β Β Fluorescent screen
4.Β Β Β Β Glass tube or envelope
5.Β Β Β Β Base
A schematic diagram of CRT, showing its structure and main components is shown in the figure below.

Since I want to explain each and every parts of the CRT in detail, I will split this topic into 3 parts.
