a cathode that is a source of electrons without being heated
Wikipedia
Cold cathode
A cold cathode is a cathode that is not electrically heated by a filament. A cathode may be considered "cold" if it emits more electrons than can be supplied by thermionic emission alone. It is used in gas-discharge lamps, such as neon lamps, discharge tubes, and some types of vacuum tube. The other type of cathode is a hot cathode, which is heated by electric current passing through a filament. A cold cathode does not necessarily operate at a low temperature: it is often heated to its operating temperature by other methods, such as the current passing from the cathode into the gas.

cold cathode
A cold cathode is a cathode that operates within a vacuum tube without being heated by a direct electrical filament. This is achieved by a process called thermionic emission, where free electrons are given out into the surrounding space. Cold Cathodes are used in a wide variety of electronic devices such as gas discharge tubes, sensors, and X-ray tubes.
