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.

29th Summer Research Program
for High School Juniors

LLE's Summer High School Research Program, now in its 29th year, involves students in many areas of investigation. The goal of this program, directed by Dr. Stephen Craxton, is to excite high school students about careers in the areas of science and technology by exposing them to research in a state-of-the-art environment. Shown above are four of the students with their projects. In the upper left is Ben Chaback (Byron Bergen High School), advised by Jim Knauer, with his Cherenkov-radiation neutron time-of-flight detector, which will measure neutrons on OMEGA experiments. In the upper right is Yujia Yang (Brighton High School), advised by Stephen Craxton, with one of her designs for future experiments on the National Ignition Facility. In the lower left is Claire Guo (Penfield High School), advised by Arijit Bose and Reuben Epstein, with a hydrodynamic simulation used to predict x-ray images. In the lower right and advised by Troy Walker and Greg Brent is Meshach Cornelius (Gates Chili High School) with a setup that monitors the deterioration of OMEGA flash lamps. More information about the Summer Research Program for High School Juniors can be found here.

Around the Lab

Laser-Driven Magnetized Liner Inertial Fusion

Until recently, most of the research into nuclear fusion (which holds the promise of creating unlimited, clean power production) focused on either magnetic confinement (low plasma density) or inertial confinement (high plasma density). However, hybrid techniques, such as magneto-inertial fusion utilizing targets shown above, are gaining increased attention since their smaller size, energy, and power density requirements are proving to be cost effective.
