    Abstract: Electron emission materials consisting of carbides, borides, and oxides, and related mixtures and compounds, of Group IVB metals Hf, Zr, and Ti, Group IIA metals Be, Mg, Ca, Sr, and Ba, and Group IIIB metals Sc, Y, and lanthanides La through Lu are used in electrodes. The electron emission materials include ternary Group IVB-IIIB, IVB-IIA, and IIIB-IIA oxides and quaternary Group IVB-IIIB-IIA oxides. These electron emission materials are typically contained in a refractory metal matrix formed of tungsten, molybdenum, tantalum, rhenium, and their alloys, but may also be used by themselves. These materials and electrodes have high melting points, low vapor pressures, low work functions, high electrical and thermal conductivity, and high thermionic electron emission and field emission properties.

    Abstract: The present invention relates to an electron gun cathode mount adapted at one end to secure a thermionic cathode and at the other end to be connected to an attachment member, wherein the electron gun cathode mount is structured so as to be capable of, when in use, reducing heat transfer from the thermionic cathode to the attachment member, and the material forming the electron gun cathode mount has a thermal conductivity of less than 10 Wm−1K−1 at the operating temperature of the thermionic cathode in a direction from the thermionic cathode to the attachment member. The present invention also relates to an electron gun assembly having the electron gun cathode mount installed therein.
