Silicon field emitters with two-layer metal-fullerene coatings for diagnostic gyrotrons

Field emitters are attractive for use in diagnostic gyrotrons destined for the DNP/NMR spectroscopy. They should provide durable work of the gyrotrons at currents more than 20-30 mA. The paper demonstrates prospects of the use of the developed by the authors multi-tip silicon emitters with metal - fullerene coatings for this application.
