A figure of merit of an ozone generator is the efficiency of ozone production, given in g/kWh, and this has been measured against gas pressure, gas flow rate, the magnitude and polarity of the voltage pulse, the pulse repetition frequency, electrode configuration, pulse length and pulse shape.","PeriodicalId":11163,"journal":{"name":"Digest of Technical Papers.

Such conditions exist in a variety of situations including chemical warfare threat scenarios, semiconductor processing, and mobile sources.

Emphasis has been placed on the capacitor-based pulse forming network (PFN) as the primary means of energy storage and pulse shaping. Defining and understanding the electrical and mechanical performance characteristics of high energy density capacitors is critical for both the PFN designer and overall weapons system engineering. Aerovox Type LM power capacitors (2.4 MJ/m/sup 3/) were evaluated under the projected Navy operating scenarios, including rep-rate and burst modes. The Aerovox Type LM capacitors, first used in the US Army 8.5 MJ Pulsed Power Module in 1991, are known to be nonlinear with respect to capacitance and voltage. Additionally, the charge/discharge efficiency is known to be lower for this capacitor than for other, lower energy density capacitors. The life characteristics of the capacitor have been established under normal operating conditions. This paper discusses the performance of the Aerovox Type LM capacitors in both normal and fault mode conditions. The parameters discussed include temperature variations, voltage reversal and peak current performance. Thermal stability and fault mode performance for the power capacitor is also defined.","PeriodicalId":11163,"journal":{"name":"Digest of Technical Papers.

The paper also reports on a preliminary application of these ideas to the Sinus-6 electron beam accelerator. We present simulation results which show that a simple nonlinear model using static neural networks is sufficient to accurately model the input/output behavior of the Sinus-6 driven backward wave oscillator (BWO).","PeriodicalId":11163,"journal":{"name":"Digest of Technical Papers.

In the proceedings of the Ninth IEEE Pulsed Power Conference, the authors published results from system development tests. At this time, they have fielded seven tests in which the focus was on either vacuum switching or load physics. Four of the tests concentrated on the performance of a plasma flow switch (PFS) which employed a l/r mass distribution in the PFS barrel. Of the four tests, two had dummy loads and one had an implosion load. In addition, one of the tests broke down near the vacuum dielectric interface, and the result demonstrated what Procyon could deliver to an 18 nH load. The authors summarize PFS results and the 18 nH test which is pertinent to upcoming solid/liquid liner experiments. On their other three tests, they eliminated the PFS switching and powered the Z-pinch directly with the HEPP system. From the best of these direct drive tests, they obtained 1.5 MJ of radiation in a 250 ns pulse, their best radiation pulse to date. They also summarize direct drive test results. More details are given in other papers in this conference for both the PFS and direct drive experiments, and an updated analysis of their opening switch performance is also included. The remainder of this paper describes the parameters and capabilities of their system, and they use the data from several experiments to provide more precise information than previously available.","PeriodicalId":11163,"journal":{"name":"Digest of Technical Papers.

Parametric trade-off is made for the prime power battery and the coil. It is shown that the minimal volume of the battery-coil system with a Brooks coil is achieved at a ratio of their volumes 3:2, respectively. For such systems, a jellyroll coil is preferable to a pancake one in view of a higher transfer efficiency. At very high battery power density, a pancake coil may be a right choice due to a lower mechanical stress. The fringe field of cylindrical and quasitoroidal coils was calculated using dipole approximation. Measurements of the discharge efficiency and fringe field are in a good agreement with the theoretical analysis.","PeriodicalId":11163,"journal":{"name":"Digest of Technical Papers.
