[en] A nuclear method for determination of energy and intensity of a proton beam is proposed to use for investigation of collective ion acceleration by space charge wave arisen in an intense relativistic electron beam (REB) at its temporal and spatial modulation. It is proposed to register the proton beam by using nuclear reactions 11B(p,α)8Be, 9Be(p,α)6Li at the proton beam assistance to produce alpha particles, which should be detected with solid state detectors

[en] The conception 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 centre dot 106 cm-3 was formed. The periodic magnetic field with 12% modulation was created by a sequence of aluminium 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

[en] Low-frequency modulation of a high-current relativistic electron beam (REB) and acceleration of ions in the first section of a collective ion accelerator as studied experimentally. This modulation was obtained due to periodic compensation of a virtual cathode charge by plasma ions. An ion flow was produced by an electric field of virtual cathode when plasma assists. Plasma was formed by the four Bostick plasma guns placed at equal distance along the periphery of the drift chamber. The low-frequency modulation with depth 10 % at frequency 46 MHz was obtained. The ion energy was measured using the magnetic analyzer. The ion energy that probably was obtained in the potential well of the virtual cathode exceeded the REB energy

[en] The parameters of the intense relativistic electron beam (REB), being a base element of the ion accelerator concept, were measured at the exit of the first section of a collective ion accelerator. The experimental studies of a REB current passing through metal foils of a different thickness were carried out. Using the obtained dependence of beam current attenuation on the foil thickness and the calibration curves (tables) of the dependence of penetration lengths on the particle energy, the energy distribution function of REB electron was determined and it is represented as a histogram. The kind of plasma resulting in a short circuit of the magnetically-insulated diode was determined
