Electrons are small negatively charged particles emitted by a hot tungsten filament. By having a large potential (voltage) difference between the cathode (the filament) and the anode, the electrons can be accelerated to almost the speed of light. The negatively charged electrons are accelerated, through a vacuum, towards the positive anode and are steered through a hold in the anode to form an intense electron beam. Materials to be treated are loaded on to a conveyor belt, passed under the electron beam and then unloaded. They are then ready for the customer to use. Safety of personnel is equally important in electron beam plants.
