An ion microprobe technique of analysis for manganese and other potentially detrimental impurities in machined cathode nickel alloy buttons is described. This nondestructive method does not jeopardize the subsequent performance characteristics of the nickel alloy pellet as a substrate for the barium-strontium oxide emitter material. This analytical technique is currently used as a standard quality assurancequality control procedure in the fabrication of cathode assemblies of traveling-wave tubes for space applications. Author
