Welcome to LLE

The Laboratory for Laser Energetics (LLE) of the University of Rochester is a unique national resource for research and education in science and technology. LLE was established in 1970 as a center for the investigation of the interaction of intense radiation with matter. The National Nuclear Security Administration funds LLE as part of its Stockpile Stewardship Program.

Measuring the Crystal Structure of HED Materials: X-Ray Diffraction at the Omega Laser Facility

X-ray diffraction (XRD) is a quantitative tool for characterizing a material's atomic structure that exploits the periodicity of atomic arrangements to produce constructive interference of x rays at specific angles scattered from parallel planes of atoms in a sample. Atomic positions within the crystal determine the x-ray peak positions and intensities. The resulting diffraction pattern is the Fourier transform of the electron density distribution and offers critical details about structures, phases, textures, and other structural parameters, such as average grain size, crystallinity, strain, and crystal defects.
