[en] The electron beam with a virtual cathode in the bounded system with feedback was studied with the help of PIC simulation. Different types of nonlinear behavior were found. The typical structures were recognized and the effect of feedback on the structure formation was investigated. Relations between nonlinear oscillations and structure formation and interaction are discussed. (author). 5 figs., 7 refs

[en] The mechanisms of excitation of ultra-wideband electromagnetic pulses (EMP) by short pulses of high-current relativistic electron beams were proposed and investigated. It is shown that the transformation efficiency of the bunch kinetic energy to the excited energy of the EMP can be very significant. (author). 2 figs., 4 refs

[en] Pulsed beams of fast deuterons and impurity or admixture ions emitted from high-current PF-type facilities operated in different laboratories are dealt with. A short comparative analysis of time-integrated and time-resolved studies is presented. Particular attention is paid to the microstructure of such ion beams, and to the verification of some theoretical models. (author). 5 figs., 19 refs

[en] Five papers presented at the conference and dealing with beam-driven strong Langmuir turbulence are reviewed and discussed. (P.A.). 11 figs., 13 refs

[en] The behavior of the electron pitch-angle was investigated by analytical and numerical methods for the case of a magnetically insulated diode with a ribbon geometry. It is shown that at the boundary of the adiabaticity of the electron motion the angle can be multiply reduced by choice of a special inhomogeneity of the magnetic field. Analytic expressions for the final pitch-angle of the beam electrons are given. (author). 2 figs., 3 refs

[en] The new current concentrator on multimodule ''Angara-5-1'' was designed for low impedance loads (imploding liners). The optimization of the concentrator design was based on the optimum relation between effects of inductance and electron losses in vacuum magnetically insulated transmission lines. The design with a small diameter magnetic separatrix was chosen for eight unit current addition in vacuum. (author). 4 figs., 4 refs

[en] The scientific programme of the conference carved the physics and technology of intense beams of charged particles, from basic experimental and theoretical problems of beam generation, transport and interaction with various media, up to beam and pulsed power applications in science and in industry. The breakdown of the papers by main topical groups is as follows: radiation sources, Z-pinches, accelerate related topics, astrophysics, ICF, ION Beam Physics, ION DIODES, ION RINGS, Beam plasma systems, diagnostic and others. This volumes contains 160 contributions, out which 133 have been input to INIS

[en] Time-dependent measurements of the magnetic field distributions in diode, plasma opening switch, and Z-pinch plasmas, based on the observation of the Zeeman effect or of the ion acceleration, are reviewed. Relatively high spatial resolution is obtained by locally doping the plasma with the desired species. Besides information on the device properties the measurements allowed for determining the plasma conductivity and for investigating the field penetration mechanism. Determination of the current density allowed the electron drift velocity to be known. (author). 4 figs., 16 refs
