The utility model belongs to a glow discharge electrode and particularly discloses an embedded glow discharge electrode. The embedded glow discharge electrode comprises a hollow flange, a vacuum electrical lead, an electrode tip and a shielding case; the electrode tip and the shielding case are positioned on the one end of a vacuum side of the vacuum electrical lead; the electrode tip is arranged within the shielding case; one side of the shielding case sleeves the vacuum side of the vacuum electrical lead; and the other side of the shielding case is an opening. The embedded glow discharge electrode can avoid direct exposure of plasma of derterium and tritium, has a low leakage danger, and guarantees the safety and reliability of a thermonuclear fusion experiment. |
