CFTF - Carbon Fiber Technology Facility
Oak Ridge National Laboratory is home to the Department of Energy's (DOE) Carbon Fiber Technology Facility (CFTF)—a 42,000 sq. ft. innovative technology facility. The CFTF offers a highly flexible, highly instrumented carbon fiber line for demonstrating advanced technology scalability and producing market-development volumes of prototypical carbon fibers, and serves as the last step before commercial production scale.
The facility, with its 390-ft. long processing line, is capable of custom unit operation configuration and has a capacity of up to 25 tons per year, allowing industry to validate conversion of their carbon fiber precursors at semi-production scale.
CNMS - Center for Nanophase Materials Sciences
The Center for Nanophase Materials Sciences (CNMS) at Oak Ridge National Laboratory (ORNL) integrates nanoscale science with neutron science; synthesis science; and theory, modeling, and simulation. Operating as a national user facility, the CNMS supports a multidisciplinary environment for research to understand nanoscale materials and phenomena.
CSMB - Center for Structural Molecular Biology
The Center for Structural Molecular Biology at ORNL is dedicated to developing instrumentation and methods for determining the 3-dimensional structures of proteins, nucleic acids (DNA/RNA) and their higher order complexes. The tools of the CSMB will help understand how these macromolecular systems are formed and how they interact with other systems in living cells. The focus of the CSMB is to bridge the information gap between cellular function and the molecular mechanisms that drive it. The suite of tools being developed by the CSMB includes:
Isotope Labeling Laboratories for cloning, gene expression, purification and characterization of labeled biological macromolecules are planned; our Bio-Deuteration Lab is currently operational and accepting proposals.
Computational Techniques have been developed for the study of macromolecular complexes by SANS. Combined with selective Deuterium-labeling, it is now possible to develop detailed structural models that will enable the understanding of function.
Another computation technique developed for the study of calculates solution small-angle X-ray and neutron scattering intensity profiles by ORNL-SAS. This makes it possible to develop from a wide variety of structures, including atomicresolution models of proteins and protein complexes, low-resolution models defined in any manner, or combinations of both.
Neutron diffraction, spectroscopy and scattering are excellent tools for studying biological systems because neutrons interact differently with hydrogen and its isotope deuterium. As a result, it is possible to:
pinpoint individual hydrogen positions in proteins
probe the structure and dynamics of proteins, nucleic acids and membranes
characterize higher order complexes
These studies use neutrons to address questions that have not - or cannot - be answered by other techniques.
SANS can be used to study biological systems under near physiological conditions, providing insight into interactions within complexes and conformational changes in response to stimuli. Through the use of specific deuterium labeling SANS makes it possible to highlight and map components within larger complexes (e.g. viruses, ribosome). The SANS instruments at ORNL's High Flux Isotope Reactor and Spallation Neutron Source will open new opportunities for studying conformational changes and molecular processes on biologically relevant timescales.
HFIR - High Flux Isotope Reactor
Scientific investigation with neutrons gives researchers unprecedented capabilities for understanding the structure and properties of materials important in biology, chemistry, physics, and engineering. ORNL provides two of the most powerful neutron science facilities in the world—the High Flux Isotope Reactor and the Spallation Neutron Source. The HFIR produces one of the brightest steady-state neutron streams on Earth, and the SNS produces the world's most intense pulsed neutron beams. Through materials research, scientists are discovering remarkable ways to address our energy needs, such as superconducting power cables that eliminate power-transmission losses and prevent outages, liquid transportation fuels produced from biomass, and magnetic refrigerators that use half the energy of conventional appliances.
To bring such technologies into common use, researchers need to be able to view materials from the atom-to-atom scale to a full systems view. Developing these advanced materials requires manipulating the properties of alloys at the atomic level, and neutron scattering is a key tool in this quest.
Neutrons show where atoms are and what they are doing at scales smaller than the best electron microscopes. They let researchers see in real time how the atomic lineup in a material shifts with changes in temperature, pressure, and magnetic or electronic fields. They trace the electron motions that give materials properties such as magnetism or the ability to conduct electricity—all essential information in the quest for energy savings.
Satisfying the world's growing hunger for energy requires finding ways to use power more frugally and developing methods for sustainably producing additional energy. Neutron scattering aids the creation of new materials engineered for both purposes.

OLCF - Oak Ridge Leadership Computing Facility
Computational science plays a very important role in many things that we see in our daily life. There's the design of aircraft, for instance, or the fundamental elements of industrial design. The virtual environment provides a much quicker way for us to improve our understanding of older problems and break ground in our understanding of new phenomena with ramifications for how we live our lives. Machines like Titan and activities like the Titan project will be the vehicles that allow us to explore these fundamental things in computational science. They will provide a framework for better product design, new and innovative technologies, and new materials. And they will enable new insights into how very complex, nonlinear systems work; that, again, has implications for a lot of the technologies that we take for granted.
OLCF is a user facility that recognizes that its products are scientific discovery and technical innovation, and we will achieve this vision working with strong partners. These partnerships will be developed through our calls for proposals and our outreach efforts to the scientific, technology, and industrial communities. To broaden the scope of leadership computing, we need to engage through our networks, through our relationships, and encourage users from new communities that can take good advantage of these resources to move us forward in scientific discovery, industrial competitiveness, and sustainability. Partnerships and alliances are a big part of what is important about our research. In terms of challenges, clearly we're at a cusp in technology moving to hybrid architectures. This implies a lot of hard work by a lot of people. But it also is a game changer.
SNS - Spallation Neutron Source
SNS is an accelerator-based neutron source in Oak Ridge, Tennessee, USA. This one-of-a-kind facility provides the most intense pulsed neutron beams in the world for scientific research and industrial development.
The 80-acre SNS site is located on Chestnut Ridge and is part of Oak Ridge National Laboratory.
Although most people don't know it, neutron scattering research has a lot to do with our everyday lives. For example, things like medicine, food, electronics, and cars and airplanes have all been improved by neutron scattering research.
Neutron research also helps scientists improve materials used in a multitude of different products, such as high-temperature superconductors, powerful lightweight magnets, aluminum bridge decks, and stronger, lighter plastic products.
To support SNS's unprecedented capability, a world-class suite of instruments is being developed that makes optimal use of SNS and that is suited to the needs of users across a broad range of disciplines. Instruments are available to researchers with varying degrees of experience, from new graduate students and first-time neutron users to experienced users with an interest in instrument design.
