Abstract

This paper reports on the progress made in developing a practical illumination system to replace argon candles. The basic concept--inexpensive, disposable, modular, surface discharge lamps that provide a flexible illumination geometry and which can be sized to match the impedance of the pulse forming network (PFN)--was described in the previous paper. Since then, the pulse shape and energy output have been measured for the complete system for the three different 19 kJ PFNs, having characteristics times of 70 microsecond(s) , 200 microsecond(s) , and 1 ms. Exposure tests confirmed that the illumination level is sufficient for color photography at 2 Mfps with a Cordin 330A and for 10 ns exposures with an IMACON 468. As the illumination source for plate fragmentation tests using live explosives, the system created `high quality images' and proved to be a useful tool that was easily integrated into the test procedure. The laboratory demonstration system has since been converted into a production model that has been installed in an instrumentation van at Eglin AFB to provide illumination at various ranges.
