英文摘要：
Physical processes that determine the generation of ion beams with a high emission current density in electrohydrodynamic emitters are considered. Electrohydrodynamic effects, which are manifested in the features of ion emission, and the kinetics of ion interaction in high-density beams are discussed. The factors that determine the size of the emission zone, stability of emission at high and low currents, cluster generation, increase in energy dispersion, and decrease in beam brightness are analyzed. The problems of the practical maintenance of the stable functioning of the EHD emitters are considered. The practical applications of EHD emitters are considered.
