Lawrence Livermore National Laboratory (LLNL) Director Kim Budil and other LLNL staff joined Department of Energy (DOE) Deputy Secretary David Turk, National Nuclear Security Administration (NNSA) Administrator Jill Hruby, DOE Under Secretary for Science and Innovation Geraldine Richmond, DOE Director of the Office of Critical and Emerging Technologies Helena Fu, U.S…

Machine learning optimizes high-power laser experiments

Commercial fusion energy plants and advanced compact radiation sources may rely on high-intensity high-repetition rate lasers, capable of firing multiple times per second, but humans could be a limiting factor in reacting to changes at these shot rates. Applying advanced computing to this problem, a team of international scientists from Lawrence Livermore National…

Manufacturing optimized designs for high explosives

When materials are subjected to extreme environments, they face the risk of mixing together. This mixing may result in hydrodynamic instabilities, yielding undesirable side effects. Such instabilities present a grand challenge across multiple disciplines, especially in astrophysics, combustion and shaped charges — a device used to focus the energy of a detonating explosive…

Accelerating material characterization: Machine learning meets X-ray absorption spectroscopy

Lawrence Livermore National Laboratory (LLNL) scientists have developed a new approach that can rapidly predict the structure and chemical composition of heterogeneous materials. In a new study in ACS Chemistry of Materials, LLNL scientists Wonseok Jeong and Tuan Anh Pham developed a new approach that combines machine learning with X-ray absorption spectroscopy (XANES) to…
