Electrons are generated in a vacuum enclosure by heating the cathode, a negatively charged emitter, to its thermionic emission temperature causing electrons to “boil off” the cathode. As the temperature is increased, more electrons are emitted from the cathode until a maximum emission level is reached. This cloud of electrons is shaped into a beam by an electrostatic field created by a negatively charged bias cup and a positively charged anode. The combination of all three of these components constitute an electron beam gun.
