 gas-filled tube, also known as a discharge tube, is an arrangement of electrodes in a gas within an insulating, temperature-resistantenvelope. Gas-filled tubes exploit phenomena related to electric discharge in gases, and operate by ionizing the gas with an appliedvoltage sufficient to cause electrical conduction by the underlying phenomena of the Townsend discharge.

The voltage required to initiate and sustain discharge is dependent on the pressure and composition of the fill gas and geometry of the tube. Although the envelope is typically glass, power tubes often use ceramics, and military tubes often use glass-lined metal. Both hot cathode and cold cathode type devices are encountered.
