At 12:00 PM EST on Friday, December 7th 2018, all LLE web sites will go offline due to an electrical power shut down that will affect
all areas of the Laboratory. LLE web sites may start to come back online Saturday evening, December 8th and all web services
should be restored no later than 8:00 AM EST on Monday, December 10.

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.

Alumni Snapshot

Maria Alejandra Barrios
Senior Data Scientist, In-Q-Tel

Dr. Barrios obtained her B.A. in Physics, Mathematics, and Philosophy from Gettysburg College and her Ph.D. in High-Energy-Density Physics and Plasma Physics from the University of Rochester in 2010. Her graduate thesis was titled: "Precision Equation of State Measurements on Hydrocarbons in the High Energy Density Regime" and her thesis supervisors were Profs. Thomas Boehly and David Meyerhofer. Dr. Barrios conducted her graduate research on the OMEGA Laser System at the Laboratory for Laser Energetics under a Frank J. Horton Fellowship.

Two LLE Scientists Elected to
APS Fellowship

Senior Scientist Wolfgang Theobald, a member of the Omega Experiments group, and Mingsheng Wei, Manager of the National Laser Users Facility, were each elected to Fellowship of the American Physical Society (APS). Fellowship is a distinct honor for each of the recipients as it is conferred by their peers in recognition of outstanding scientific achievement. No more than one half of one percent of the APS membership is elected to Fellowship annually. Wolfgang was recognized for "pioneering experiments and seminal contributions in suprathermal electron generation and transport in laser-driven inertial confinement fusion plasmas including fast-ignition and shock-ignition implosions." Mingsheng was recognized for "contributions to the field of experimental high-intensity laser–plasma interactions and in particular for improved understanding of hot-electron transport with regard to applications such as fast-ignition fusion and ion acceleration."

A Novel Statistical Model to Triple the Fusion Yield in Direct-Drive Laser Fusion

Accurate predictive capabilities are essential in the quest for thermonuclear ignition. In support of these predictive models, the Laboratory for Laser Energetics (LLE) has developed a novel statistical approach used to predict and design multiple cryogenic deuterium–tritium (DT) implosions on the OMEGA Laser System. This approach has led to the tripling of the fusion yield to its highest value for direct-drive laser fusion of DT-layered targets.
