Acceleration of Thin Plates by Exploding Foil Techniques
A technique for the acceleration of thin plates to high velocities by exploding foils has been developed. These plates, primarily Mylar and Lucite up to 3 in. by 3 in. and from a few mils to 1/4 in. thick, are used to produce high- impulse, short-time loading of materials for the purpose of material dynamics at high pressures. Velocities up to 5 · 105 cm/sec have been achieved. A brief description of equipment including the capacitor system, cameras, and backlighting, etc. is given, as well as a more detailed description of the construction of the transducer and its characteristics. Methods of velocity determination are described. High-speed photographs of these high-velocity plates are presented.
