Abstract
The passage of a concentrated beam through the extraction system of a beam plasma generator is investigated on the basis of analysis of variations in the beam diameter and emittance. Evolution of these parameters is analyzed in the final section of the extraction device, which is characterized by the high density gradient of the supplied gas. Much attention is given to the influence of the magnetic field on the features of electron beam propagation. It is demonstrated that focusing is favorable to decreasing not only the beam transverse size, but also the growth rate of the beam emittance.
