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.

Calorimetry Measurements of Liquid Deuterium Supercooling in a
Direct-Drive Target

Roger Gram, a Research Engineer at LLE, is shown adjusting the position of a temperature sensor that is attached to a NIF-size cryogenic target. The inset shows the target assembly in more detail: the 3-mm-diam target, while supported and filled through a stainless-steel tube, is thermally attached to a copper foil that contains a heater and temperature sensor. The size and mass of the components are kept to a minimum, allowing the heat that is released when liquid deuterium freezes to be measured. This experimental platform is being used to evaluate methods to seed the growth of a deuterium crystal from the condensed liquid while preventing the liquid from supercooling. The goal is to optimize the process used to form a single-crystal defect-free ice layer inside a target.

Around the Lab

An Enduring Partnership

Research scientists at the Laboratory for Laser Energetics and physicists, chemists, and computer scientists at the State University of New York (SUNY) at Geneseo have enjoyed a dynamic and enduring partnership for close to 20 years, culminating in the formation of the Nuclear and Plasma Diagnostics Development Laboratory on the Geneseo Campus. Staffed by six faculty members and more than a dozen undergraduate students, the Laboratory engages in research projects on a part-time basis throughout the academic year and full-time during the summer months.
