The work objective is to develop the scientific bases of composite cathode materials making with low values of electron work function and high values of thermionic current density (to 1000 A/cm2) for their using in rocket-space engineering and other branch of industry. The results of obtaining and thermionic properties research of new cathode composite materials BaxSr1-xHfO3-W, ErB12, LuB2 are presented in the report. It has been achieved that for the most effective thermionic material 80 % Ba0,75Sr0,25HfO3 - 20 % W (by mass) the current density equals 1014 A/cm2 at T = 1620 K. For the first time the spectral emissivity of erbium dodecaboride single-crystals are presented. The results of improvement and making of new generators generation and Hall plasma accelerators for space and engineering purposes are presented. The magnetic system of plasma generators has been simulated. Product Description popup.authors Ісаков О. Воронович Д.О. Кислицин О.П. Колесник В.В. Колесник В.П. Комозинський П.А. Луньов І.В.
