There is provided a metallic tape supporting a mercury vapor releasing material, preferably Ti.sub.3 Hg, admixed with a non-evaporable getter metal, preferably an alloy of 84% Zr--15% Al, contained within a continuous series of depressions within the tape. The depressions form a successive series of pairs of depressions preferably each having an oval shape. Each pair of oval shaped depressions is separated by a distance greater than the distance separating the individual oval shapes. The tape can then be cut between each pair of depressions to form a small strip containing two depressions. Such a small strip can then be folded through an angle of approximately 180.degree. about an axis, in the plane of the tape midway between the depressions, perpendicular to the tape length. This folded strip can then be welded to a support and used as a cold cathode electrode in a miniature fluorescent lamp. The cathode can be heated during a manufacturing process to release mercury and subsequently act as a cold cathode and getter device.

A color television picture tube comprising a glass cone portion, a glass window portion and a metal screen cone. The metal screening cone is located within the volume defined by the glass cone portion and the glass window portion. At least a major portion of the metal screening cone is distanced away from the glass cone portion. An evaporable getter device comprising two parallel linear channel holders having U-shaped cross-sections, each containing a source of evaporable getter material is placed between the metal screening cone and the glass cone portion. Evaporable getter device is mounted on the metal screening cone by means of support legs. Getter material vapors from the getter device evaporate in a direction substantially parallel to a line formed by the nearest intersection of the glass cone portion and the glass window portion.
