Abstract
We performed a series of dynamic loading experiments on iron with pressures of 5-40 GPa at the Trident Laser Laboratory. We used 2.4 ns laser pulses of varying shapes and irradiances of 2 to 1000 GW/cm2 to load a 5-mm diameter region of rolled iron foils that were 25-50 microns thick. The temporal characteristic of the laser irradiance was tailored to produce shock or quasi-isentropic loading histories. Line-imaging VISAR was used to time-resolve free surface velocities. In several experiments, two different thickness samples, placed side-by-side, were subjected to the same irradiance history. We describe the experiment configuration, analysis, and results.
