Abstract
The paper presents formulated requirements to the gas-dynamic device designed for working substance feeding into the ionization zone of plasmas facilities. The role of geometrical factors in formation of a supersonic flow is determined, as well as, the role of gasdynamic factors in attainment of necessary parameters beyond the forming element. The conditions for gas-dynamic flow clustering minimization in the course of outflow in vacuum
