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.

Multi-Institutional Effort to Study
"Extreme Matter"

The University of Rochester is leading a seven-institution collaboration that promises to significantly broaden human understanding of "extreme matter"— matter that exists under pressures far higher than either on or inside Earth. The collaboration, with local principal investigators Profs. Pierre Gourdain, Gilbert "Rip" Collins, and Dustin Trail, includes Cornell, Michigan, Idaho State, Iowa, Princeton, and Stanford. The research team will develop an instrument called a high-amperage driver for extreme states, or HADES, which will allow scientists to produce and study extreme matter.
  The project is fully supported by the National Science Foundation, which awarded the University a $1.1 million grant in August. While extreme matter doesn't exist naturally on or inside Earth, it's quite common in the universe, especially in the deep interiors of planets and stars. Prof. Gourdain notes that HADES will lead to new knowledge about star formation and planetary collisions, the potential for life on other planets, and the properties of materials that make up deep-space objects.
  A rendering of HADES and further information can be seen here. More information about high-energy-density physics research at the University 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.
