    • A German scientist, E.Goldstein modified the discharge tube and passed an electric current through it.
    • He found that positively charged rays were emitted from the anode in the discharge tube. These rays were called 'Canal Rays'.
    • When an electric field was applied, these rays deflected towards the negatively charged plate. Thus, Goldstein concluded that an atom contains positively charged particles along with the electrons.
    • These positively charged particles were named as 'protons' by a British scientist, Ernest Rutherford.
    • Canal rays were also called anode rays since they emitted from anode (electrode connected to positive terminal of high voltage source) in the gas discharge experiments using perforated cathode.
