Abstract: We investigate the operation of multitip silicon field emitters with new-type bilayer metal–fullerene protective coatings in technical vacuum. The experiments indicate that such cathodes ensures emission current densities averaged over the cathode surface of about 0.5 A/cm$^2$ and can be used in high-voltage devices including microwave electronic instruments as well as portable X-ray sources.
