This report documents the initial development of the High Pressure Particulate Physics HP3 facility. The facility is anticipated to allow precision impact of two flat plates at a very high degree of precision with minimal misalignment when completed. A 60 mm smooth bore powder gun will be used to achieve this capability. Impacts will occur under high vacuum conditions. The gun will fire projectiles that carry a faced material at the nose and will impact a stationary target at the muzzle end. High precision time-resolved diagnostics shall record dynamic impact responses in materials of interest under high strain rates. Our goal is to perform well controlled and repeatable experiments to provide accurate equation of state data and constitutive properties of materials of interest to the Air Force to develop robust computational models, which are physically based. This new thrust at AFRLRW is addressing a recommendation made by the Scientific Advisory Board in 2007.
