Cathode ray :It is a beam of electrons in a vacuum tube traveling from the negatively charged electrode (cathode) at one end to the positively charged electrode (anode) at the other, across a voltage difference between the electrodes. They are also called electron beams.
The electrode at the negative end is called a cathode. The electrode at the positive end is called an anode. Since electrons are repelled by the negative charge, the cathode is seen as the "source" of the cathode ray in the vacuum chamber.
