Abstract

The operation of tungsten tip field emitters coated by activated fullerenes in technical vacuum is studied. Ways of emitter training to provide the self-reproducibility of the coatings and their long service life under intense ion bombardment in wide ranges of pressures, from 2 × 10−8 to (5–7) × 10−7 Torr, and emission currents, from (1.5–2.0) to (10–20) μA, are developed.
