    Recent advances in the physics and technology of the modulated intense relativistic electron beams (IREB's) are reviewed in this paper. Bunched dense electron beams can be used to construct high-power RF sources, which may critically affect future progress in fusion technology. In this paper a system is described in which electrical energy can be converted from a single pulse of relatively long du... View full abstract»

    A theoretical model for the unit cross section of a 1-atm unbounded arc was used to investigate arc behavior. The electrical source was taken as a dc voltage and resistance in series. Because the simulated arc is not radially bounded, the arc V-I characteristic is found to be time varying and dependent on the source values. The results of exercising the model also show that the central temperature... View full abstract»

    Flow phenomena occurring in repetitively pulsed gas-flow spark gaps have been investigated experimentally and compared with theory. Optical flow diagnostics were obtained after the current pulse using schlieren photography, a flashlamp, and a framing image converter camera (ICC). Experimental results reveal nearly spherical arc-generated shocks propagating symmetrically with respect to the arc deb... View full abstract»

    Cited by:  Papers (2)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1135 KB)

    Magnetic-field propagation from a plasma to a probe through a partially ionized layer of low conductivity is studied. The model includes dispersive properties of the layer and a radiation condition in the probe wall dielectric. A mixed problem of initial and boundary conditions is solved by Laplace transform techniques. The results are applied to the discussion of magnetic probe reliability in pla... View full abstract»

    A KrF laser (248 nm) is used to volume preionization trigger a 40-100-kV, > 10-kA, 100-ns spark gap switch. This method of triggering creates reproducible and axisymmetric spark columns having low temporal and spatial jitter. A short pulse (< 5 ns) tunable dye laser and a Mach-Zehnder interferometer are used to obtain spatial and temporal measurements of the spark column. The spatial resolution of... View full abstract»

    We have measured the ion flux for different electrode materials in a vacuum arc. The vacuum arc has a point-plane geometry. The ion species in the generated plasma are identified using a time-of-flight (TOF) spectrometer. Ion species that have been generated to date include D+, Mg+, Mg++, Al+, Al++, Al+++, Ti+, Ti++, Ni+, Ni++, Cu+, Cu++, Zn+, Zn++, and In+. We found that in all cases, the ion flu...

    Induced scattering of plasma electrons by spontaneously created soliton is studied experimentally with the method of coincident analysis. The scattering model and the scattering time rate (STR) are obtained theoretically. From the comparison of experimental and theoretical results, experimental evidence of induced scattering and electron heating by the soliton is obtained. View full abstract»

    Dielectric-filled waveguides may be advantageous for heating reactor-grade tokamak plasmas, due to their compactness and power-handling capability. We present a theoretical analysis of coax excitation and plasma impedance for a dielectric-filled rectangular waveguide. The plasma reflection coefficient is obtained by matching plasma and waveguide fields at the interface. The numerical results show ... View full abstract»

    A numerical study of current neutralization and its effect on charge transport of a 0.175-MeV 6-kA 30-ns relativistic electron beam (REB) in argon at low pressure of 10-2-1 torr is presented. Contribution of two-stream instabilities to plasma conductivity is included in the calculations. The calculations show that energy coupled from beam to plasma is about 1-3 percent in the pressure range 0.1-1 ... View full abstract»

    The recently reported Graneau experiments on electrodynamic explosions in liquids, which reveal anomalous longitudinal electrodynamic forces of the order of 104 times greater than expected, verify the need for a term in the law of electrodynamics that corresponds to the ion/electron mass ratio. This confirms an earlier theoretical interpretation of the anomalous cathode reaction forces found in th... View full abstract»
