Using a simultaneously initiated cylindrical explosive, a coaxial magnetic flux-compression generator (FCG) was designed to test high-current-gain limitations. A coaxial design with a lossless gain of approx. 100:1 was chosen for its efficiency, relative simplicity, and calculability. Theoretical design included modeling as well as 1-D and 2-D hydrodynamic and MHD calculations. A 69.3-cm cylinder of PBX-9501 high explosive, 20.3 cm in diameter, was used to drive the Al armature into a Cu stator. The initial current supplied by a capacitor bank was approx. 3 MA which produced a final current approx. 75 MA. Details of the experiment and a comparison with calculations are presented.

The explosively-pumped magnetic flux compression generator (FCG) is a pulsed-power current amplifier powered by an explosion. This thesis surveys FCGs, demonstrating their general operation; develops a new magnetic-field-strength-based model for FCGs in the form of a generalized cylinder that more accurately captures losses to magnetic diffusion than commonly employed circuit models, but maintains simplicity in the form of a low order DAE; develops a simplified means of calculating the inductance of FCGs, providing a bridge between the field-based and circuit models; presents a design of a full loop FCG system (a topology underserved by existing literature) and an experimental setup to verify the designed loop generator; and proposes a class of non-explosive magnetic flux compression generators. The designs and models herein provide new tools and jumping-off points for further research into FCGs, particularly in the miniaturized systems gaining popularity and in the potential for reusable flux compression power sources.

While the basic operating principles of Helical Magnetic Flux Compression Generators are easy to understand, the details of their construction and performance limits have been described only in government reports, many of them classified. Conferences in the field of flux compression are also dominated by contributions from government (US and foreign) laboratories. And the government-sponsored research has usually been concerned with very large generators with explosive charges that require elaborate facilities and safety arrangements. This book emphasizes research into small generators (less than 500 grams of high explosives) and explains in detail the physical fundamentals, construction details, and parameter-variation effects related to them.

Explosive pulsed power generators are devices that either convert the chemical energy stored in explosives into electrical energy or use the shock waves generated by explosives to release energy stored in ferroelectric and ferromagnetic materials. The objective of this book is to acquaint the reader with the principles of operation of explosive generators and to provide details on how to design, build, and test three types of generators: flux compression, ferroelectric, and ferromagnetic generators, which are the most developed and the most near term for practical applications. Containing a considerable amount of new experimental data that has been collected by the authors, this is the first book that treats all three types of explosive pulsed power generators. In addition, there is a brief introduction to a fourth type ix explosive generator called a moving magnet generator. As practical applications for these generators evolve, students, scientists, and engineers will have access to the results of a considerable body of experience gained by almost 10 years of intense research and development by the authors.
