cathode ray

a stream of electrons emitted by a negative electrode when it is bombarded by positive ions, in a gaseous discharge device called a cathode ray tube. The ray is focused and deflected by electromagnets that control the position at which it strikes a screen coated with a phosphor, creating a visible pattern.

cathode ray

A ray composed of negatively charged electrons discharged by a cathode through a vacuum, moving in a straight line and producing x-ray photons upon hitting solid matter.
