ABSTRACT:
A discharge tube comprises a vessel containing rare gas; a plurality of electrodes (having a cathodic part and anodic part therein) and so arranged tandem in said vessel that a glow discharge is kept in a discharge gap between each said cathodic part and said anodic part of the preceding electrode, and that an optical path is allowed to let through each negative glow part of said glow discharge adjacent to said cathodic part; means to apply a dc voltage across every said discharge gap in series; and means to supply metal vapor to one of said glow discharge at the most low potential end of said means to apply dc voltage, whereby metal ions formed in said one of said glow discharge are carried down throughout said vessel.
