Abstract

Charged particle radiography was invented at Los Alamos and 800 MeV proton radiography has become a key diagnostic used to study dynamic material properties. This measurement technique has been used on hundreds of experiments at LANSCE and developed around the world.  Recently, due to the interest of using electrons as the direct radiographic probes at MaRIE, charged particle radiography has been extended to the use of high energy electrons.  Because of the difference in the mass of the electron compared to the mass of the proton, the radiography processes are substantially different and well suited to the study of fast dynamic processes in relatively thin systems, such as those planned at the Multi-Probe Diagnostic Hall (MPDH) at MaRIE.  

In this presentation we will discuss the basics of charged particle radiography, the benefits of different probe types and the challenges ahead to combine all probe information at the MPDH to fully characterize dynamic systems at MaRIE.
