Megabar Isentropic Compression Experiments (ICE) using High Explosive Pulsed Power (HEPP)
thesis
posted on 2018-10-18, 08:04 authored by Douglas G. TaskerIn the shock physics community there is significant interest in the acquisition of
accurate isentropic Equation of State (EOS) data at megabar pressures (i.e. at ≈50 GPa and above). A relatively new technique, called the Isentropic Compression Experiment or ICE, uses rapidly rising magnetic fields to compress materials to high
stresses of the order of 50 GPa and above over a few hundred nanoseconds. This
work was first performed on the Z-machine at the Sandia National Laboratory in
Albuquerque, NM, USA. Using ICE, the Sandia researchers were able to obtain
relatively accurate EOS data at large stresses in a planar geometry.
This thesis describes the explosive pulsed power (HEPP) version of the ICE
method, which employs a simple and compact HEPP apparatus. Every aspect of the
HEPP–ICE work is presented, from theory to component development, to
experimentation and data analysis. [Continues.]
