Abstract:

Reliable diagnostic techniques were developed to measure the mass and velocity of hypervelocity particles projected by an exploding-foil gun. Velocities were increased from 20,000 ftsec to better than 35,000 ftsec as a result of improved gun design and modifications to the energy system, including the installation of an electrically triggered switching system. The Electro- Optical 6-frame Kerr cell camera was also evaluated. A program to measure the electrical parameters of the system and to correlate them with photographic data was instituted, and a theoretical model for the partition of impact energy of a hypervelocity particle was begun. Once sufficient data have been taken with the improved particle projection and diagnostic technique, a more comprehensive theoretical program will be instituted.
