Abstract

The results of studying the intense ion beam propagation with peak energy up to 330 keV are presented. The ion beam was injected into the metal tube made from stainless steel in the form of a hollow cone. It was found that the ion beam focused due to neutralizing the space charge and reducing the divergence of ions. Neutralization of the beam space charge was investigated by measuring its electric potential. The average energy density of a beam increased up to 2.9 J/cm² over the beam cross-section in the focal plane. The ion beam current density in the tube rose by a factor of 3 in comparison with geometric focusing. The analysis of the surface structure of the ion beam spot obtained on the stainless steel AISI 304 plate was done.
