Formation of high-density electron flows by electron-optical systems with multilayer field emitters.

This paper presents the results of study of multilayer emitters consisted from the hafnium and platinum layers. The operation of sheet and annular in cross section cathodes in technical vacuum is demonstrated. Investigated cathodes provide high currents of field emission at emission currents density up to 200 - 400 A/cm2.
