Shock temperature measurements in ammonia
Abstract
Our first shock temperature measurements on a cryogenic target are reported for NH3. A new fast optical pyrometer and a cryogenic specimen holder for liquid NH3 were developed to measure shock temperatures of 4400 and 3600 K at pressures of 61 and 48 GPa. These conditions correspond to those in the ice layers in Uranus and Neptune. The shock temperature data are in reasonable agreement with an equation of state based on an intermolecular potential derived from NH3 Hugoniot data.
