Abstract
The process of formation of point sources of charged particles based on growing of the nanoprotrusions on surface of tungsten carbide field emitters was studied. The protrusions were grown by simultaneous action on the emitters of strong electric fields and high temperatures. Such nanoprotrusions allowed to reducemission angles very considerably and to emit both electrons and various ions.
