Construction Details of CRT
1) Electron gun:
It is very simple device which mainly produces thin electron beam. It is the combination of Heater, Cathode and the Grids. All this components are situated at the base of the tube. The heater heats the cathode and then the cathode emits a lot of electrons which make an electron cloud. The electron gun is analogous to the pen. In different parts of the electron gun different types of voltages are required. These voltages vary within the range 200-600 Volts. The electron gun receives voltages from the receiver which is connected with the base pins of the CRT.
2) Heater:
The heater is mainly used to heat the cathode. It is made of metals and twisted in shape. It heats the cathode indirectly. It needs 6-24 Volts dc or ac supply voltage.
