Abstract
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.
