Due to their interaction with end current leads during implosion, high-energy cylindrical liners driven by disk EMG currents can gain considerable longitudinal asymmetry, like, for example, in the joint RF-US experiment HEL-1 (1996), which agrees with computations using various 2D techniques. This paper using 2D DRAKON and MEDUZA computations demonstrates the possibility to cardinally improve the longitudinal compression symmetry for this liner type as compared to that in HEL-1. The influence of liner geometry and strength parameters as well as ponderomotive unit end current lead parameters on the liner compression longitudinal symmetry is studied. Data is obtained which is needed for selection of the ponderomotive unit for the second potential joint VNIIEF/LANL explosive magnetic experiment (HEL-2) in order to achieve a high longitudinal symmetry of impact of the cylindrical solid liner on the target at liner velocity up to 15 km/s.

The features of a design and characteristics of special vacuum tubes, electron-beam valves (EBV), intended for switching in high-power high-voltage electrotechnical systems are considered. It is shown that EBV can be effectively used in power supplies of dust cleaning electrostatic precipitators (ESP). The possibility of using EBV in the pulse power supply system with streamer discharge for cleaning from oxides is considered and the concept of combined effluents cleaning from oxides and dust is represented.

Current debris models are able to predict the growth of the space debris problem and suggest that spacecraft must employ armor or bumper shields for some orbital altitudes now and that the problem will become worse as a function of time. The practical upper limit to the velocity distribution is on the order of 40 km/s and is associated with the natural environment. The velocity distribution of the man-made component peaks at 9-10 km/s with maximum velocity in the 14-16 km/s range. Experience in space has verified that the "high probability of impact" particles are in the microgram to milligram range. These particles can have very significant effects on coatings, insulators and thin metallic layers. The surface of thick materials becomes pitted and the local debris component is enhanced by ejecta from the impact events. In this paper, the HYPER facility is described which produces a reasonable simulation of the man-made space debris spectrum in a controlled environment. The facility capability is discussed in terms of drive geometry, energetics, velocity distribution, diagnostics, and projectile/debris loading.

The Atlas system consists of 96 Marx generators, arranged in a circle. Sets of four generators feed a tri-plate transmission line, and the tri-plate lines in turn feed a central load region. The space between the plates is a nominal 2.00 cm (0.787 inch). This spacing and support of the central plate are provided by a set of insulators referred to as the tri-plate standoff insulators (TSI). The insulators were designed to provide the required mechanical support, ease of replacement or removal for maintenance, and the electric field gradient standoff. Two materials were selected: one was chosen because it has reasonable mechanical properties and a dielectric constant close to that of oil (polypropylene /spl epsiv/=2.3); the other material was selected because of its increased mechanical strength, even though the dielectric constant is higher than that of oil (Nylon MC 901 and 907 /spl epsiv/=3.7). Testing of the insulators was performed in a three-foot diameter tri-plate assembly. The test setup accepts four insulators at a time. The nominal operational voltage for the tri-plates is 240 kV at a t/sub eff/ of 0.87 /spl mu/s. The testing was performed at up to 450 kV with a t/sub eff/ of 2.8 /spl mu/s. The insulators were successfully tested until oil breakdown between the plates was reached, with no insulator flashover.

An experiment was carried out on a small gas-puff Z-pinch plasma device with capacitor bank of 16 /spl mu/F and charging voltage 22 kV. Discharge current was measured by Rogowski coil. A compact Thomson ion energy analyzer was installed in the discharge chamber for determining the energy spectra of ion beam emitted from the Z-pinch plasma. The energy spectra of argon ion beams with single, double and triple charges were determined using the analyzer. A Mach-Zehnder laser interferometer was installed to measure the electron density and the movement of Z-pinch plasma. The electron density of the plasma just before pinch instant is larger than 9.00/spl times/10/sup 18//cm/sup 3/, the corresponding radius and the pinch velocity of the plasma are 1.42 mm and 1.86 cm//spl mu/s, respectively. The yield and the time variation of X-ray emitted from the pinch plasma were also measured.

Atlas is a pulsed-power facility being designed at Los Alamos National Laboratory to perform high-energy density experiments in support of Science-Based Stockpile Stewardship and basic research programs. Atlas will consist of 24 individual maintenance units, each consisting of 4 240-kV Marx units. Maintenance units are contained in large oil tanks arrayed in a circle about a central target chamber. Total stored energy of the capacitor bank will be 23 MJ. Maintenance units will discharge through an output shorting switch into a vertical tri-plate transmission line, and from there into a transition area/collector inside a large vacuum chamber. An overview of mechanical design aspects of the Atlas machine is presented. These include maintenance unit design and design of the tri-plate transmission line and transition region. Findings from fabrication and testing of prototype systems are discussed.

A key element in the design of a coaxial generator system is the simplicity of the geometry. The clean cylindrical geometry allows us a reasonable chance at modeling RANCHERO performance using the authors' 1D and 2D MHD modeling codes. The results of numerical simulations have been compare to several tests of the RANCHERO system in a variety of configurations. Recent comparisons of 1D calculations with the REOT-2 data have been extremely good and suggest that the generator is behaving in a very 1D like nature until reaching 90-95% of peak current. Differences between calculated current and measured performance during the last 3 mm (out of 70 mm) of flux compression may be a consequence of either the EOS for SF/sub 6/, 2D effects, or both. This study examines the existing models and attempt to provide a robust integrated model which can then be used to drive design studies, pre- and post-shot analysis, and predict performance parameters for slight variations of the base design of RANCHERO.

Possibility of modification of MC-1 cascade generator of 10 MOe range reproducible magnetic fields in order to convert it into high-power electromagnetic energy source, providing more than 50 MJ with energy density of /spl sim/0.2 MJ/cm/sup 3/ in the volume by a diameter about 2 cm and length of /spl sim/1 m, is considered for the first time. Such a generator could be useful for investigations of dense magnetized plasma, interaction of charged particle beams with magnetic field and plasma, studying of possibility of X-ray lasers creation and other processes, which require high electromagnetic field at simultaneously high values of its density.

Switching conditions influence on dielectric strength of internal insulation of high-current triggered vacuum switches with trapezoidal-rod electrode system is investigated. Investigations were carried out for two switching regimes. In the first regime electrode erosion occurs mainly in a vapor phase where the electrode surface remains smooth after switching. In the other switching regime a drop phase of electrode erosion prevails and considerable electrode surface damage takes place. It follows from statistical processing of experimental data that the breakdown voltage distribution is described with a Weibull distribution law satisfactorily. Influence of gap and electrode material on dielectric strength of triggered vacuum switches is considered.
