Abstract

A method of fabricating an electrode is disclosed, wherein the electrode comprises a copper holder defining a cavity in a forward end. An emissive element and separator assembly is positioned in the cavity. An intermetallic compound is formed between the emissive element and the separator by heating a relatively non-emissive material until it melts and dipping the emissive element therein before cooling the assembly. As a result, the intermetallic compound is formed significantly faster than by conventional methods.
