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.

World's Youngest Fusioneer Visits LLE

Eighth-grader Jackson Oswalt, heralded as the youngest person in America to build a working nuclear fusion reactor, gave a seminar talk at LLE. Now 14 years old, the Memphis native completed the project a day before his thirteenth birthday. His reactor, which he built in his home, uses heated deuterium gas to produce a plasma, a process that includes heating the gas with 50,000 V. The reaction takes place in a vacuum chamber, which is created with a powerful turbomolecular pump. "I realized that certain things that I thought were impossible for someone my age aren't impossible," he says about the achievement. In addition to his presentation, Oswalt received a tour and attended talks by LLE senior staff during his visit.

Around the Lab

OMEGA Laser System Second Line-of-Sight Project

Achieving controlled thermonuclear fusion, an energy source with the potential to provide a virtually unlimited source of clean energy, requires diagnostics to better understand the complex process that takes place in inertial confinement fusion (ICF) experiments. Due to the 3-D nature of these experiments, measurements are needed over multiple orthogonal lines of sight to maximize the coverage required to infer 3-D performance metrics.
