Charged Particle Radiography

Dr. Frank Merrill
Los Alamos National Laboratory


Los Alamos National Laboratory has used high energy protons as a probe in flash radiography for a decade. In this time the proton radiography project has used 800 MeV protons, provided by the LANSCE accelerator facility at LANL, to diagnose over three-hundred dynamic experiments in support of national and international weapons science and stockpile stewardship programs. In addition, 24 GeV protons, provided by the Alternating Gradient Synchrotron at Brookhaven National Laboratory, have been used to study the capability of proton radiography at higher beam energies. Through this effort significant experience has been gained in using charged particles as direct radiographic probes to diagnose transient systems. The results of this experience will be discussed through the presentation of data from experiments recently performed at the LANL pRad facility as well as results from previous electron radiography work performed at the Idaho Accelerator Center.
