Using the Los Alamos high explosive pulsed power (HEPP) system, isentropic equation of state (EOS) data may be obtained for a wide range of materials. Current pulses with risetimes of {approx}500 ns and current densities exceeding 400 MA/m, create continuous magnetic loading of samples at megabar pressures. We will summarize the technique and the problems that had to be overcome to perform the HEPP-ICE experiments at these pressures. We will then present our EOS results obtained with the conventional Lagrangian analysis and the Hayes 'Backward' integration method, and compare the data with the published principal isentrope of OFHC copper.
