AbstractAbstract
[en] A new way to transform a quite large part of magnetic energy stored in a Z-pinch plasma into X-rays was first proposed by Rudakov: using an axial magnetic field Bz, a large part of the energy is expected to be transferred by axial electron conductivity to a converter which is placed perpendicularly to the axis of the plasma in order to produce a bright soft X-ray source. In this paper, experimental results obtained on the 'AMBIORIX' generator are presented. A hollow cylindrical liner of helium was driven by a current reaching 2 MA in 50 ns. The implosion was studied with and without axial magnetic field, a steady regime of implosion is observed using Bz = 0.3 T. The plasma parameters and the heating of an aluminium converter were measured using various diagnostics. A detailed analysis of The experimental data were analyzed in detail and compared with the results of numerical simulation. (author). 4 figs., 6 refs

[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

AbstractAbstract
[en] The physical basis is discussed of electronic devices whose operation is based on the beam or dissipative instability of the azimuthal surface waves (ASW). The ASW are electromagnetic surface waves with extraordinary polarization (with field components Er, Eφ, Hz), propagating across the axial external steady magnetic field in the cylindrical metal waveguide with cold plasma filling. The ASW fields are described by Maxwell equations. To solve the problem, the authors used the Fourier method and numerical simulation of the equations obtained. The ASW excitation was examined under conditions of beam and dissipative instabilities due to the electron beam motion. The correction to ASW eigenfrequencies caused by the waveguide chamber noncircularity was also studied. ASW delaying leads to a negative frequency correction. The ASW energy can be emitted from the narrow slot in the metallic chamber of the waveguide. The optimum wavenumber range was found where the increment values are much greater than those of the ASW decrement caused by their energy radiation. (author). 2 figs., 3 refs

AbstractAbstract
[en] The results Monte Carlo simulations of an intense neutron source based on muon catalyzed fusion process are presented. A deuteron beam is directed onto a cylindrical carbon target, located in vacuum converter chamber with a strong solenoidal magnetic field. The produced pions and muons which originate from pion decay are guided along magnetic field to a DT-synthesizer. Pion production in the primary target is simulated by means of Intranuclear and Internuclear cascade codes developed in INR, Moscow, while pion and muon transport process is studied by using a Monte Carlo code originated at CERN. The main purpose of the work is to calculate the pion and muon utilization efficiency taking into account the pion absorption in the primary target as well as all other losses of pions and muons in the converter and DT-cell walls. Preliminary estimations demonstrate the possibility to reach the level of 1014 n/s/cm2 for the neutron flux. (J.U.). 3 tabs., 4 figs., 8 refs

AbstractAbstract
[en] The results are given of studies on a plasma X-ray source providing 2.5 krad of radiation dose per pulse over an area of 100 cm2 in the quantum energy range between 20 and 500 keV. The pulse duration was 100 ns. The spectral radiation distribution was obtained under various operating conditions of plasma and diode. A Marx generator served as the starting power source of 120 kJ with a discharge time of T/4=10-6 s. A short electromagnetic pulse (10-7 s) was shaped using plasma erosion opening switches.

AbstractAbstract
[en] Meeting goals for waste cleanup will require new technology with improved environmental attractiveness and reduced cost. Plasma technology appears promising because of the high degree of controllability; capability to process waste without the adverse effects of combustion; and a very wide temperature range of operation. At the Plasma Fusion Center at the Massachusetts Institute of Technology, a range of plasma technologies are being investigated. 'Hot' thermal plasmas produced by DC arc technology are being examined for treatment of solid waste. In conjunction with this activity, new diagnostics are being developed for monitoring arc furnace operating parameters and gaseous emissions. Electron-beam generated plasma technology is being investigated as a means of producing non-thermal 'cold' plasmas for selective processing of dilute concentrations of gaseous waste.

AbstractAbstract
[en] A technique for ion beam space-charge neutralization with pulsed electron beams is described. The intensity of multiply-charged ions produced with a laser ion source can be enhanced or decreased separately with electron beam trains of MHz repetition rate. These are generated with ferroelectric cathodes, which are pulsed in synchronization with the laser ion source. The pulsed electron beams guide the ion beam in a similar way to the alternating gradient focusing of charged particle beams in circular accelerators such as synchrotrons. This new neutralization technology overcomes the Langmuir-Child space-charge limit and may in future allow ion beam currents to be transported with intensities by orders of magnitude higher than those which can be accelerated today in a single vacuum tube.

AbstractAbstract
[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
