cathode ray

Stream of fast-moving electrons that travel from a cathode (negative electrode) towards an anode (positive electrode) in a vacuum tube. They carry a negative charge and can be deflected by electric and magnetic fields. Cathode rays focused into fine beams of fast electrons are used in cathode-ray tubes, the electrons' kinetic energy being converted into light energy as they collide with the tube's fluorescent screen. The electrons are emitted from the heated metal cathode by a process called thermionic emission.
