A stream of accelerated electrons. Electrons are negatively charged parts of atoms; they surround the atomic nucleus. They can be gathered into a beam that produces high-energy radiation to treat cancer.
Flow of electrons generated in a cathode ray tube by the electron gun and aimed at the back of the screen. The electrons excite phosphors causing them to glow various colors, thus forming an image on the screen.
The stream of electrons generated by the electron gun and accelerated by the accelerator guide.
