| Abstract Scope |
Imaging density distribution of materials in extreme conditions is crucial for advancing many fields from hypersonic vehicles to inertial fusion energy. For example, the National ignition Facility (NIF) recently achieved increasing yields of inertial confinement fusion (ICF) potentially opening the pathway towards practical inertial fusion energy (IFE). Voids and other defects in the IFE fuel capsule material has been shown to create hydrodynamic instabilities that can reduce IFE yield. For IFE and other applications, the ability to see the projected density of the material in extremes requires ultrafast temporal and nanometer spatial resolution. To address these challenges, our team has implemented x-ray phase contrast imaging (XPCI) at the Linac Coherent Light Source (LCLS) Matter in Extreme Conditions (MEC) instrument studying shockwave-void interactions. By comparing experimental images with hydrodynamic code simulations, we find good agreement that can lead to further improvements in quantitative understanding of the hydrodynamics of defects in materials. |
