Cathode Ray Tube: Electron Source & Ionization

When my Tv shoots electrons from the cathode ray tube , where do these electrons come from and is it ionizing whatever they come from.

The came from a filament. The electrons are ejected via thermionic emission.

It is not ionizing for the filament. The filament is connected to ground.

ok thanks for the answer , so then are the electrons cycled back through the circuit somehow
