We report on our investigations of a pulsed high power streamer corona reader using a simple coaxial discharge tube for industrial gas treatment processes, such as ozone generation and flue gas cleanup. For industrial usages of these processes, higher discharge power density is favorable to achieve higher productivity. As a first step of research aiming at the higher discharge power density, we examined experimentally characteristics of the repetitive pulsed streamer corona discharge using dry air as feed gas. As a result, the dependency that the discharge current decreases with repetition rate and increases with gas flow rate has been found. The maximum discharge power density of about 100 W/l (/spl sim/25 kV, /spl sim/75 A, /spl sim/100 ns, 170 pps, 0.3l) was obtained in this experiment. The gas temperature rise at this condition was about 20/spl sim/25 %. Because it is not so high as to affect gas treatment badly, it will be possible to operate at still higher discharge power density. We also measured generated ozone in this experiment and the lowest ozone energy cost obtained was 9/spl sim/10 Wh/gO/sub 3/, which was lower than that of a commercial silent discharge type ozonizer.

The Pichugin pulser (named after its Russian inventor) is a compact, high reliability vector inversion generator. Although consisting of many stages, the Pichugin pulser has the distinct advantage that only one inversion switch is required. One-switch operation gives the generator its high degree of reliability and is accomplished by using transformer coupling between the generator stages. If efficient transformer coupling is maintained, the generator can be made very compact. This investigation reports on the design, performance, and characterization of a compact 500 kV, approximately 1 J Pichugin pulser. Without an output peaking switch (or spark gap) the output risetime of the pulser is approximately 0.5 /spl mu/s. Shorter, nanosecond risetimes have been measured with the use of an output peaking switch. These types of pulsers are used in our laboratory to trigger various spark gaps and multi-channel surface discharge switches with a good performance record and a high degree of reliability. The Pichugin pulser is an attractive alternative to conventional Marx-bank pulser design.

The authors report here on a joint experimental shot series with teams from Russia and the United States. The program was based largely upon the MC-1 generator, a high magnetic field explosive flux compressor, developed by the Pavlovskii group at Arzamas-16. The series was of historical interest in that it was carried out in a Los Alamos security area, the first time for such a collaboration. They discuss a number of technical issues involved in matching Russian hardware with Los Alamos explosives, initiation systems and the seed field energy source, as well as comparison of field measuring diagnostics furnished by the two teams. They conclude with a discussion of an investigation of the high temperature superconductor YBa/sub 2/Cu/sub 3/O/sub 7/ (YBCO), employing these generators. The low temperature critical magnetic field of this material was found to be 340/spl plusmn/40 T, as determined from a 94 GHz microwave interferometer developed for this purpose.

A method and technique for measuring the pulsed power electron and ion beam energy density (W in J/m/sup 2/) absorbed by a target as well as the main elastic constants of material have been proposed and realized. The method developed is based on the authors' laser-interferometric and theoretical investigations of the space-time characteristics and amplitudes of thermoacoustic waves excited by pulsed power electron beams in various solids: metals; alloys; semiconductors; amorphous and crystalline dielectrics; and composites. Experimental conditions under which compression-expansion pulse of the longitudinal wave and flexural oscillations of a sample can be observed simultaneously, have been found. As the experiments have shown, the amplitude of thermoelastic flexural wave as well as the amplitude of longitudinal pulse is proportional to W. The authors reconstruct the profile of beam dose absorbed by material and determine W using available standard samples with known elastic constants and Gruneisen's parameter and the interferometry data on longitudinal and flexural thermoacoustic waves.

Simulations of vacuum electron flow in a coaxial transmission line with and without ion emission are compared with each other and with experimental data from Gamble II. The simulation without ions shows large current losses just downstream of an impedance discontinuity. Simulations with ions show that the vacuum electron current past the impedance discontinuity is increased by the presence of ions. The losses are much more distributed than in the simulation without ions. The experimental data shows a more distributed current loss that is similar to the case where ion emission is allowed. This suggests that ions may be present and playing a role in the experiment.

A rapid fire railgun launcher has been designed and fabricated and a single-shot prototype has been tested for the Cannon Caliber Electromagnetic Gun (CCEMG) System. Three, five round salvos of 185 g launch packages are to be accelerated to 1850 m/s at a rate of 5 Hz. The 2.25 m launcher has a 30 mm round bore equivalent, rectangular geometry and is water-glycol cooled. Rapid fire operation is achieved by driving the launcher with multiple 835 kA pulses provided by the CCEMG compulsator. The launcher is a series augmented railgun and has demonstrated breech efficiencies over 50%. A high CCEMG system efficiency is in part attributable to the use of a solid armature and is enhanced by having a structurally stiff railgun. Historically, a railgun's stiffness was proportional to its weight. Laboratory based railguns that have respectable mechanical properties have required massive structures that are nowhere near meeting the requirements of future vehicle integration and weaponization. The Cannon Caliber railgun design incorporates a directional preloading mechanism, ceramic sidewalls and a composite overwrap which together give it a structural stiffness dominated by high modulus ceramic with an overall mass of only 273 kg. These characteristics make the Cannon Caliber launcher one of the most "fieldable" railguns built to date.

The Defence Research Agency, with support from Physics International, has performed a detailed study of the use of the pulsed power system at the Kirkcudbright Electromagnetic Launch Facility as a driver for electrothermal guns. The study addressed the performance of the bank, as is, driving representative ET loads, evaluated possible modifications of the bank to improve its performance into certain loads, and estimated the implications (cost, schedule, and effect on operation into EM loads) of such modifications. This paper describes the performance of the bank in its present configuration and discusses the types of loads for which performance is limited, as is. Loads for which modifications may be desired are then described. Possible modifications are presented and predicted performance with the modifications in place is reviewed.

The paper details power capacitor bank experiments performed to assess the performance of a pulsed power plasma erosion opening switch (PEOS). A description is given of the PEOS, which was of an inexpensive and expendable design, and was intended for use as the final stage of a flux compressor output conditioning circuit. Techniques using automatically operating exploding foils, as both opening and closing switches, condition the 9 /spl mu/s quarter-wave output pulse from the capacitor bank to a 400 ns pulse to the PEOS. An outline is given of the computer modelling and the experimental procedures used to establish the optimum operating conditions, and results are presented which illustrate the behaviour of the PEOS.

Calculations and experiments have shown that the repetitive high-current electron beam (HCEB) generation of ozone from the air is an order of magnitude more favorable energetically than producing ozone by a persistent electron beam. But it is less advantageous than the production of ozone by the electric-discharge method (w/sub sp//spl sim/13 kw h/kg), if one takes into account the efficiency of converting energy into a beam (about 50%). However, specific power intakes fall as the electron energy rises because of an increase in the free path length of electrons in the air. Calculations for RUSLAN (E=700 keV, I=5000 A, t=50 ns), and SIBERIA (E=1000 keV, I=5000 A, t=50 ns) accelerators provide evidence that these machines are becoming competitive in power intake with electric-discharge accelerators. Virtues of the ozone production process involving the use of a repetitive accelerator include the simplicity in design, low cost, and reliability of the air oxygen-to-ozone-conversion unit.
计算和实验表明，重复大电流电子束(HCEB)从空气中产生臭氧在能量上比持续电子束产生臭氧有利一个数量级。但是，如果考虑到将能量转换成光束的效率(约50%)，它不如电放电法(w/sub sp//spl sim/13 kw h/kg)产生臭氧有利。然而，由于电子在空气中的自由路径长度的增加，电子能量的上升导致了比功率的下降。对RUSLAN (E=700 keV, I=5000 A, t=50 ns)和西伯利亚(E=1000 keV, I=5000 A, t=50 ns)加速器的计算提供了证据，证明这些机器在功率吸收方面与放电加速器具有竞争力。使用重复加速器的臭氧生产过程的优点包括设计简单、成本低和空气氧-臭氧转换装置的可靠性。
