摘要：

Results of investigation of emission properties, life time, elemental composition of the surface and change of these properties during the life of dispenser cathodes covered with films on basis of osmium and rhenium are presented. Dispenser cathodes covered with films (Re-Hf and Os-Hf) can be used as effective sources of thermo and secondary electrons.
