In 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.
