Beamline 9-BM-B,C: X-ray Absorption Spectroscopy
X-ray Science Division, APS
Materials Science, Chemistry, Environmental Science, Catalysis, Physics
Description
The XSD Spectroscopy Group operates the bending magnet beamline 9-BM to serve the materials science and chemistry user communities. It provides a focused, tunable x-ray beam for XAFS and XANES experiments with special capabilities for lower energy x-rays and quick XAFS at higher energies. It also has extensive capabilities for in-situ work. We are currently accepting mail-in samples that require minimal onsite preparation. Opportunities for in-situ work are limited and require close coordination with beamline staff.
