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.

Workshops at LLE

LLE hosted the 11th International Laser Operations Workshop (ILOW) on 26–28 September, and the 5th National Implosion Stagnation Physics Workshop on 27–28 September. The objective of the ILOW workshop is to optimize the productivity and efficiency of the large laser facilities worldwide, which improves the quality, quantity, and breadth of scientific research performed at these facilities. Scientists and engineers from the following facilities attended: the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory (LLNL), the Orion Facility and the Rutherford Appleton Laboratory of the United Kingdom, the Laser Mégajoule (LMJ) and LULI facilities of France, the three Extreme Light Infrastructure sites (ELI) of the Czech Republic, Hungary and Romania, the Z backlighter facility at Sandia National Laboratories (SNL), the Stanford Linear Accelerator Center at Stanford University in California, and the Texas Petawatt System at the University of Texas at Austin.

The 5th National Implosion Stagnation Physics Workshop was co-chaired by LLE Senior Scientist, Sean Regan and MIT Research Scientist, Johan Frenje, who stated that, "The overarching goal of the NISP effort is to substantially advance our understanding of the physics of the stagnation process and state of the fuel and ablator near and at stagnation." Scientists from LLE, Imperial College London, Massachusetts Institute of Technology, General Atomics, SNL, University of Nevada-Reno, Los Alamos National Laboratory, LLNL, and the Naval Research Laboratory participated in the workshop.

Advancement of Hybrid Fluid-Kinetic Modeling Efforts for High-Energy-Density–Physics and Inertial Confinement Fusion Science

Adam Sefkow, Assistant Professor of Mechanical Engineering and Physics at the University of Rochester and senior scientist at the University's Laboratory for Laser Energetics (LLE), compares his research in high-energy-density physics (HEDP) and inertial confinement fusion (ICF) to that of a detective determined to solve an enigma. He builds on the achievements of other scientists; interprets data learned from experiments at LLE, Lawrence Livermore National Laboratory, and Sandia National Laboratories; and recognizes how often something significant can be learned from unexpected results. The recipient of both an Early Career Research Program award from the U.S. Department of Energy and the 2017 Excellence in Fusion Engineering Award from the Fusion Power Associates, Sefkow is currently developing a hybrid fluid-kinetic multiphysics simulation code named CHIMERA.
