Abstract

A 20 mm long 8 mm diameter cylindrical tin target has been shocked to a pressure just below the β→γ phase change, using a small, low density PETN charge mounted on the opposite side of a thin stainless steel diaphragm. The density jump and shock velocity were measured radiographically at multiple points as the shock wave moved though the sample and the pressure dropped, using the proton radiography facility at LANL. This provided a quasi-continuous record along the principal Hugoniot from a peak shock velocity of 3.27 km/sec to a minimum of 3.09 km/sec. Edge release effects were removed from the data using simple tomographic reconstruction techniques. The data and analysis are presented.
