Explosion energies and life tests 1. 9-cm bore flashtubes

Measurements performed on 1.9-cm bore flashtubes constructed of both clear fused quartz and germisil quartz, all filled to a constant pressure are presented. The goal was to determine, for both types of quartz, the 100 shot explosion energy and 10,000 shot life test data at 100 and 200 j/(cm of arc length) loadings. In the course of the work, seven flashtubes, three of clear fused quartz and four of germisil quartz, were exploded at a pulse width of 3..sqrt..LC = 500 ..mu..sec. In addition, ten flashtubes, six of clear fused quartz, and four of germisil quartz were life tested to 10,000 shots also at a pulse width of 3..sqrt..LC = 500 ..mu..sec.
