Plane shock generator explosive lens
Sandia National Laboratories' design and development of an optimized Plane Shock Generator Explosive Lens (PSGEL) is detailed in this report. This PSGEL component is designed to generate a planar shock wave transmitted to perform a function through a steel bulkhead without rupturing or destroying the integrity of the bulkhead. The PSGEL component consists of a detonator, explosive, brass cone, and confinement or tamper housing. The purpose of the PSGEL component is to generate a plane shock wave input to a stainless steel bulkhead (wave separator) with a ferro-electric (PZT) ceramic disk attached to the steel on the surface opposite the PSGEL. The planar shock wave depolarizes the PZT 65/35 ferro-electric ceramic to produce an electrical output. Elastic, plastic I and plastic II waves with different velocities are generated in the steel bulkhead. The depolarization of the PZT ceramic is produced by the elastic wave of specific amplitude (10-20 kilobars) and this process must be completed before (about 0.15 microseconds) the first plastic wave arrives at the PZT ceramic. Measured particle velocity versus time profiles, using a Velocity Interferometer System for Any Reflector (VISAR), are presented for the brass and steel output free surfaces. Shock wave planarity data, using an electronic streak camera, are presented for the brass and steel wave separator free surfaces.
