The conception, proposed by Lymar, Khizhnyak, and Belikov, to use collective electromagnetic fields of space charge excited in high-current relativistic electron beam (REB), modulated in time and space, have been experimentally investigated. At plasma assistance the low frequency oscillations of 46 MHz are excited in the overcritical REB. The flow of C⁺ ions accelerated by the space charge field of virtual cathode up to 500 keV with density of 6×10⁶ cm⁻³ was formed. The fluence of ions on the collector during the ion pulse has the value 5×10⁷ particles/cm². The periodic magnetic field with 12% modulation was created by a sequence of aluminum and iron rings. After acceleration in the section with temporary and spatially modulated REB ions achieved energy 1.5 MeV and ion current 1 A.
