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.

Studying Planetary Magnetic Fields

More than 80 percent of planets are composed of metallic hydrogen. However, metallic hydrogen is one of the rarest materials found on Earth. Mohamed Zaghoo, Research Associate, and Gilbert 'Rip' Collins, Associate Director for Academics, Science, and Technology, have studied the conductivity of metallic hydrogen using experiments on the Omega Laser System to understand how planets form magnetic fields. Jupiter has one of the strongest magnetic fields in our solar system, and the "dynamo" mechanism that causes this is also present deep within the Earth. This dynamo creates our own magnetic field, making our planet habitable by shielding us from harmful solar particles. A key to Jupiter's magnetic field may lie in understanding the properties of metallic hydrogen, which surrounds Jupiter's core. More information is available in the recently published article in The Astrophysical Journal, and in on the University website.
