A variety of high-performance pulse-power systems in the 10 to 20-MJ class have been built in the last ten years or are planned in the next 3--5 years. Such systems, using capacitive energy storage, are employed in particle beam fusion, x-ray effects, x-ray physics, and plasma physics experiments. Advances in the technology of high-energy- density capacitors over the same time period has substantially decreased the cost per joule of the basic capacitor and kept the total parts count in large systems within reason. Overall, the savings in capacitor costs has about balanced the generally increasing system costs keeping the total cost of large, high-performance systems at $1--2 per joule over the period. The next step, to 100-MJ class systems, will profit from the improvements of the last decade, but there seems little reason to project a lowering of the cost per joule. In contrast, there is every reason to expect the continuously growing system costs to outstrip any savings to be realized from improvements in capacitor technology. Over the same period, explosive pulse power systems in the 10 to 20-MJ class have been employed, routinely, in plasma physics experiments. These one- shot systems currently cost about $100 K for the generator and switching and deliver energy to a plasma physics experiment in a few microseconds. Comparing only hardware costs, such systems are competitive with capacitor systems for developmental activities involving 100--200 shots -- but not for repetitive applications involving 1000's of shots. At this rate, explosive systems are competitive systems for applications involving up to 200--500 shots. In this paper, we discuss general concepts for generators and power-conditioning systems appropriate for high-energy applications. We scope two such applications and show how explosive pulse power can address those applications. And we describe one example of an explosively powered generator suitable for 100-MJ operation.

Explosive Pulsed Power System for New Radiation Sources available in PDF, EPUB and Kindle. High explosive pulsed power (HEPP) systems are capable of accessing very high energy densities and can reach conditions that are not possible with capacitor bank systems. The Procyon system was developed and used for experiments over a period of six years, and is exemplary of the capabilities of HEPP systems for state-of-the-art research. In this paper we will summarize some of the more interesting aspects of the work done in the past but will suggest ideas toward applications for future research. One of the main, unique features of HEPP systems is that they integrate easily to a particular physics experiment and the power flow can be optimized for a specific test. Magnetic flux compression generators have been an ideal power source for both high current plasma physics and hydrodynamic experimental loads. These experiments have contributed greatly to the understanding of high temperature and density plasmas and more recently to the understanding of instability growth in thick ((almost equal to)1 mm) imploding metal cylinders. Common to all these experiments is the application of a large current pulse to a cylindrically symmetric load. The resulting Lorenz force compresses the load to produce hydrodynamic motion and/or high temperature, high density plasma. In the plasma physics experiments, plasma thermalizes on axis and a black body distribution of x-rays is produced. To get better access to the radiation pulse, the load electrode geometry was modified. For example, by shaping the plasma implosion glide planes, a mass depletion region was formed along one electrode at pinch time which generated a very large voltage drop across a 1-2 mm segment of the pinch, and also produced a high energy ion beam on axis. These results were predicted by magneto-hydro-dynamic (MHD) codes and verified with framing camera and x-ray, pinhole, camera pictures. We have not previously published these features but will take another look and propose possible scenarios for studying and generating high intensity ion beams. The conditions generated in the implosion load region may be ideal for generating K and L-shell radiation via ion-atom collisions. In recent years, and in a previous conference, the simulation community has shown interest for Ar K-shell radiation and other soft x-ray sources. We will speculate on ways to use this system to generate a high fluence pulse of Ar K-shell radiation, and also to use the high intensity ion beam to study the mechanisms involved in the ion-atom collisions process. These processes can be used to enhance x-ray radiation from a variety of elements.

The generation of megagauss fields for science and technology is an exciting area at the extremes of parameter space, involving the application and controlled handling of extremely high power and energy densities in small volumes and on short time scales. New physical phenomena, technological challenges, and the selection and development of materials, together create a unique potential and synergy resulting in fascinating discoveries and achievements.This book is a collection of the contributions of an international conference, which assembled the leading scientists and engineers worldwide working on the generation and use of the strongest magnetic fields possible. Other research activities include generators that employ explosives to create ultra-high pulsed power for different applications, such as megavolt or radiation sources. Additional topics are the generation of plasmas and magnetized plasmas for fusion, imploding liners, rail guns, etc.

Pulse Power for High Energy Density Physics Experiments available in PDF, EPUB and Kindle. Pulse power technology has been supported and developed in the US over the last 4 decades by the Department of Energy in support of the nuclear weapons and energy research programs, and by the Department of Defense for advanced weapons technology and nuclear weapons effects research. Recent, changes in the priorities and orientation of these programs have made the planning and conduct of basic science experiments possible using facilities heretofore completely dedicated to a more narrow range of experimental activities. The purpose of the `Spring Workshop on Basic Science Using Pulsed Power` is to introduce high performance pulse power technology to a broader cross-section of the community and to discuss, with the community, experiments which can be planned now using currently operating systems and to begin to consider experiments which can be planned for the systems of the future.
