In a Cathode Ray Tube, the focusing anode is located

In a Cathode Ray Tube, the focusing anode is located Correct Answer Between pre-accelerating and accelerating anode

Focusing anode and PD anode:

  • The electron gun emits the electrons and forms them into a beam
  • The electron gun mainly consists of a heater, cathode, a grid, a pre-accelerating anode, a focusing anode and an accelerating anode
  • The focusing anode is located between pre-accelerating and accelerating anode.
  • The electron while passing through the control grid is accelerated by a high positive potential which is applied to the pre-accelerating or accelerating nodes
  • The electron beam is focused on focusing electrodes and then passes through the vertical and horizontal deflection plates and then goes on to the fluorescent lamp
  • The pre-accelerating and accelerating anode are connected to 1500 V, and the focusing electrode is connected to 500 V
