Electron Gun Model Answer - correct answer-- Low voltage supply heats filament causes thermionic emission/ electrons have enough energy to leave - Electrons are repulsed from the cathode (filament) and attracted towards the anode - This electric field causes electrons to accelerate - There is a hole in the anode which creates a beam for electrons that pass through - Electrons are then fired through a vacuum (to stop interfering particles) onto a fluorescent screen Photo Electric E...
