  • Abstract
    Cryogenic machining was used as a means to eliminate the conventional methyl-methacrylate infiltration process used in the manufacture of dispenser cathode matrices. The resulting surfaces were analyzed before and after impregnation to determine their suitability for dispenser cathodes.
