EXPLODING WIRE DETONATORS: SWEEPING-IMAGE PHOTOGRAPHS OF THE EXPLODING BRIDGE WIRE INITIATION OF PETN

7

TL;DRAbstract

are being prepared to provide single short pulse (2nS) laser illumination, multiple pulse laser illumination and long pulse (..mu..S) flashlamp illumination. These illuminators will allow various forms of direct micro-photography, shadow and Schlieren photography. These techniques will be used to provide direct measurement of shock velocities and histories. We are also investigating the direct measurement of pressure in and behind the shock using the spectral shift in the fluorescence of certain dyes. For this application we are building an intensified imaging spectrograph. We examine the status and plans of the laboratory and present some initial results.
