The desire to move high-energy Pulsed Power systems from the laboratory to practical field systems requires the development of compact lightweight drivers. This paper concerns an effort to develop such a system based on a plastic laminate strip Blumlein as the final pulseshaping stage for a 600 kV, 50ns, 5-ohm driver. A lifetime and breakdown study conducted with small-area samples identified Kapton sheet impregnated with Propylene Carbonate as the best material combination of those evaluated. The program has successfully demonstrated techniques for folding large area systems into compact geometry's and vacuum impregnating the laminate in the folded systems. The major operational challenges encountered revolve around edge grading and low inductance, low impedance switching. The design iterations and lessons learned are discussed. A multistage prototype testing program has demonstrated 600kV operation on a short 6ns line. Full-scale prototypes are currently undergoing development and testing.

A measurement system's components: cabling, delay line, waveform recorder, etc., degrade acquired signals and their respective bandlimited frequency responses. Compensation software corrects for this frequency-dependent spectral degradation by deconvolving the transfer function of the entire measurement system out of the measured signal spectra. This report describes methods to transfer the characteristics of a wide bandwidth repetitive sampling oscilloscope to a single-shot transient digitizer, characterize the measurement system, develop a cascaded transition-band filter, and compensate data acquired with the filtered, characterized measurement system. These procedures are easily implemented, execute quickly, and successfully compensate waveforms possessing endpoint discontinuities. Waveforms possessing endpoint discontinuities are made to appear duration-limited and continuous. The spectra for these modified waveforms are correct, including at dc. The deconvolution process introduces unavoidable noise. Filtering is applied to reduce the deconvolution noise while minimally affecting compensated waveform risetime and amplitude. Resultant compensated data retains its initial dc baseline offset with improved waveform fidelity and low noise of deconvolution.
