Source of ions of solid and gaseous substances

Sourse of ions of solid and gaseous substances under normal conditions is described. A plasma electron source is utilized for obtaining vapours of solid working substance. The ion source operates in a continuous regime under the pressure of the working substance vapour of approximately 1 Pa at T <= 1300 K. Current of an ion beam approaches 10sup(-2) A. The surce can operate in the regime of an electron gun. Tests of the source in the regime of the electron gun revealed that at extracting voltage of 10 kV electron beam current exceeds 10 mA, at extracting voltage of 20 kV current of extracted electrons is equal to 23 mA. Working gas (air) flow rate makes up 2x10sup(-2) cm3/s under atmospheric pressure
