Charged Particle Radiography for Dynamic Applications

Energetic, charged particles are a valuable tool for probing dynamic systems, as the application of a magnetic lens allows for a detector to be placed far from a dynamic event. Traditionally, relativistic protons have been used in this way at the Los Alamos Neutron Science Center's (LANSCE) proton radiography facility (pRad), to image high-explosive driven materials studies, and for potential medical imaging applications. More recently, the technique was extended to include electron radiography of thin systems, at the Idaho Accelerator Facility, and high energy electron radiography at the Stanford Linear Accelerator Center, to increase spatial resolution and visualize thinner materials. Work is underway now to implement an Achromat lens to increase the depth of focus. Electron radiography is being further extended to be driven by a self-modulated laser wakefield accelerator (SMLWFA) at the OMEGA EP facility at the Laboratory for Laser Energetics, enabling fusion-relevant instantaneous flash imaging. The same technique is also applicable to charged-alpha radiography, which can readily be used in conjunction with carbon ion therapy to visualize patient anatomy before and during treatment. The latest developments on these fronts will be discussed.
