Low-Impedance Compact Modulators Capable of Generating Intense Ultra-fast Rising Nanosecond Waveforms
Abstract
In this work, efforts were concentrated upon exploration and examinations of the impedance parameter space and output pulse characteristics of the Blumlein devices to facilitate development of reliable pulsers capable of generating intense ultra wideband electric fields. Output pulse characteristics available from our Blumlein pulsers with different number of lines, line impedances and switching devices were examined. The range of pulse characteristics that may be of interest for Bioelectric and Isomer Research applications were recorded. Issues concerning the switch longevity were studied by fabrication and testing the GaAs photoconductive switches treated with the amorphic diamond. Longevity tests were performed and results for the switch lifetime demonstrated a significant improvement with the application of amorphic diamond. In addition, we studied and surveyed various methods and geometries for non-intrusive electric field delivery and flash x-ray production. Low impedance x-ray diodes were designed and implemented. Output waveforms and x-ray generation were examined by the proper matching of diodes to Blumlein pulsers commutated by thyratrons and/or photoconductive switches. Ultra-fast rising x-ray pulses were produced and studied.
