    Abstract: A cleaning system and technique for CRT electron guns is provided in which CO.sub.2 snow is utilized to clean contaminants from the electron gun. The CO.sub.2 snow and CO.sub.2 gas are directed onto the electron gun through small orifices in nozzles arranged at angular positions relative to one another and relative to the electron gun. This enables complete cleaning of the electron gun upon the rotation and movement of the electron gun relative to the two nozzles.
