The electron beam is produced by thermionic emission in hot cathodes—electrons are liberated from a hot filament when the thermal energy is enough for electrons to exceed the filament's work function.

cathode rays are nothing but beam of electrons observed in vacuum tubes.
when electric dischargeis passed through gases at very low pressure, cathode rays are produced
2) when high voltage charge from induction coil is applied to tubes, cathode rays are produced
