Characterizing the atomic structure and chemistry complex and heterogeneous materials under in situ and operando conditions.
The Spectroscopy program at Brookhaven Lab's National Synchrotron Light Source II offers world-class capabilities for studying complex and heterogeneous materials under in situ and operando conditions using specialized x-ray spectroscopy tools. The program's scientific focus is to understand and optimize the structural and chemical features of complex materials in battery research, heterogeneous catalysis, minerals, ceramics, alloys or porous organo-minerals under non-ambient and dynamic conditions.
Program Beamlines
Beamline for Materials Measurement
BMM offers capabilities in x-ray absorption spectroscopy and x-ray diffraction for studying materials for important societal challenges in energy, health, environment, and national security. With its high-intensity photon flux and its two diverse experimental setups, BMM helps scientists unlock the mysteries of hard matter materials for battery research and electro catalysis using state-of-the-art experimental equipment.
Quick X-Ray Absorption and Scattering
The QAS beamline is optimized for characterizing the complex chemical behavior of crystalline and amorphous materials with sub-second time resolution. By combining x-ray spectroscopy with x-ray powder diffraction and optical spectroscopy, QAS serves a wide range of communities in chemistry, materials science, energy conversion, and energy storage.
Spectroscopy Soft and Tender 1, 2
Beamlines SST-1 and SST-2 offer x-ray spectroscopy, imaging, and scattering techniques for studying the behavior and properties of soft matter, hard matter, and compound materials that can be used for energy storage, energy conversion, and electronics. SST-1 and SST-2 provide a wide range of x-ray absorption and spectroscopy experimental techniques and detectors, combined with two beams of soft and tender x-rays.
Inner Shell Spectroscopy
The ISS beamline offers researchers highly advanced tools for studying chemical processes under operando conditions and material growth in situ. The beamline's high photon flux and broad-band hard x-rays offer optimal conditions for studying energy storage, energy conversion, and catalysis. The expertise of the beamline staff and instrumentation is well-aligned with battery research, electro and heterogeneous catalysis, and materials growth.
Tender Energy X-ray Absorption Spectroscopy
The TES beamline provides advanced microscopy and microbeam spectroscopy tools for investigating the detailed structure of materials using tender (1-5 keV) x-rays. TES offers user-tunable spatial resolution as well as in situ electrochemistry, and primarily serves the energy, environmental, climate, and planetary sciences.
In situ and Operando Soft X-ray Spectroscopy
The IOS beamline offers researchers specialized tools for in situ and operando spectroscopy on heterogeneous catalysis and other energy systems. Researchers can study complex chemistry and energy conversion under ambient and elevated pressure of various gases. By offering this new capability, IOS bridges the long-standing pressure gap problem in catalysis between ideal surface science experiments and industrial catalytic processes.
