Abstract
The characteristics of the high intense pulsed ion beam with energy up to 330 keV have been studied. The ion beam was extracted in the metal drift tube made in form of a cone. It was found that the metal tube provided the beam space charge neutralization up to 90% and increase in the beam current and energy density. The focusing factor of a beam current in the metal tube increased from 4.5 to 13. The mass ratio of ions propagated in the tube and in outer space had been varied. In this case, the proportion of protons in the tube increased from 75.7% to 84.7%.
