Proton Radiography at Los Alamos: Looking inside Explosions

Proton Radiography (PRAD) is a diagnostic tool that uses high energy proton beams to generate sequences of flash radiographs of fast moving objects. It has been used at Los Alamos National Lab to study such phenomena as detonation of high explosives and explosively-driven metal deformation, failure, and equation of state. PRAD is the only technique that can generate tens of frames of flash radiography data on time scales ranging from nanoseconds to hours. PRAD principles and techniques will be described, and examples of results from PRAD experiments will be presented.
