Using an Interferometer to Map Electron Density Gradients in HEDP Experiments

March 18, 2019

Pia Valdivia, Johns Hopkins University Research Scientist, is shown aligning the Talbot–Lau x-ray deflectometer for use in a National Laser Users’ Facility experiment to benchmark the ten-inch manipulator (TIM)–based diagnostic on OMEGA EP (EP-TXD). The interferometer can map electron density gradients in high-energy-density physics experiments. The experiment aimed to characterize irradiated foils by mapping the ablation front for electron density values above critical density.
