DEVELOPING MANUFACTURING TECHNOLOGY OF COMPOSITE CATHODES WITH METHOD OF PRESSING PYROLYTIC GRAPHITE WITH TRIPLE CARBONATE

In this work a manufacturing technology for a composite cathode is described. In this cathode draphite and emission-active substance forms intercalated chemical compound. These cathodes were studied in a mode of field thermo electrone emission at temperatures of 0-1100  C and anode voltages of 1 – 15 kV. The article contains results of determination of optimal pressing parameters, different methods of cathode surface processing and field emission current-voltage characteristics.

Key words: vacuum electronics, nanostructured graphite materials, field emission, field emis-sion, composite cathode, ion etching
