TWO STAGE PLASMA SOURCE FOR LARGE SCALE BEAM GENERATION

Abstract

The operation of a cylindrical plasma accelerator with an anode layer in the mode of ion space charge accumulation and the use of an ion flow accelerated by a space charge is investigated. In particular, the presence of highvoltage and diffusion modes with the formation of a secondary flow has been established. The output plasma flow current can reach 70% of the discharge current on the anode layer. The relationship between the connection scheme of the additional independent cathode and the plasma source parameters is shown.
