Abstract
PURPOSE: TO prevent sparking due to electron discharge, by forming an electron- emission preventive coating on a Wehnelt cylinder or anode.
CONSTITUTION: The impregnant substance of Ba or BaO of cathode 1 sticks to Wehnelt cylinder 3 or anode 5, which prevent the emission of thermions, so that Wehnelt cylinder 3 or anode 5 will be plated with coating 14 of titanium. Therefore, barium sticking onto titanium film 14 is removed from the surface diffused into the titanium coating, so that thermion emission and secondary-electron emission will be nearly eliminated
