Holifield's tandem electrostatic accelerator

Holifield's tandem electrostatic accelerator

The base of ORNL’s Holifield Radioactive Ion Beam Facility’s tandem electrostatic accelerator. The accelerator is located inside a 100-foot-high pressure vessel. HRIBF’s ability to create and analyze isotopes that exist for mere seconds gives researchers a unique glimpse into the inner workings of atomic nuclei, as well as how they interact with each other and with high-energy particles. Understanding these processes provides astrophysicists with insights they need to unravel the mystery of how the these processes could have created of all of the heavy elements in the universe–both in the hearts of stars and through hyperviolent stellar events, such as supernovae.

Thin-layer chromatography

Thin-layer chromatography

ORNL researchers use high-resolution, thin-layer chromatography plates to separate complicated mixtures (in this case, Ginkgo biloba leaf extracts). The separated components appear as bands under fluorescent lighting. Once separated, the components of the mixture can be analyzed using mass spectrometry. These techniques could be applied to several fields of study, including creating and using nanoscale materials to control molecular level processes in fields such as catalysis, energy conversion and materials research.

Nion UltraSTEM Electron Microscope

Nion UltraSTEM Electron Microscope

The basic principle of electron microscopy is simple: an electron beam penetrates a sample and the whole optical system is used to produce an image of the material. Thanks to the success of aberration correction, goals that were unthinkable of a few years ago are now a reality, such as the identification of single atoms in materials along with the study of their properties or 3D reconstructions of nanostructured systems and even isolated atoms. The Nion UltraSTEM is ideally suited for studying materials with atomic resolution in real space. It can produce images of crystal lattices with interatomic spacings below 0.1 nm, both in direct imaging and spectroscopy, allowing the simultaneous study of crystal structure, chemistry and even electronic and optical properties.

Standoff Laser Spectroscopy System

Standoff Laser Spectroscopy System

The system works by shining an infrared laser on a distant object. The reflected light from the object’s surface is captured by a telescope, focused onto a detector and analyzed to determine the chemical composition of the surface of the object. As an anti-terrorism tool, the device may be used to detect and identify surface residues of dangerous materials, such as chemical agents, biological agents or explosives, from distances up to 100 meters. The system has a wide array of uses from scanning ?passengers and luggage in airport terminals to searching for improvised explosive devices (IEDs) along roadways to scanning vehicles on the road or at border crossings and checkpoints.

Atomic-Scale Growth by Pulsed Laser Deposition

Pulsed Laser Deposition is used to grow oxide-based energy materials by stacking single atomic layers to design epitaxial thin films and superlattice crystals suitable for discovering new functionalities. This allows the formation of atomically-sharp interfacial structures that convert, manipulate, or store energy.

VULCAN diffractometer

VULCAN diffractometer

The optical fibers of a VULCAN detector module. The fibers transmit the light signals created by captured neutrons to photo multiplier tubes where the signals are amplified and then sent to a data acquisition system.

One of the newest and most popular instruments at the SNS is the VULCAN diffractometer. The reasons behind VULCAN’s popularity are similar to those that make the SNS so attractive: it is new, and it has unusual capabilities. VULCAN was built to take measurements on engineering materials (like a turbine blade from a jet engine or the frame of a car) under stress. VULCAN is capable of u201cseeingu201d inside the material and making three dimensional maps of the distance between atoms in critical sections. Scientists can look at these maps and determine if the atoms are being squeezed together or pulled apart—signs of stress and strain in the materials.
