Beamline 9-BM-B,C: X-ray Absorption Spectroscopy Beamline

X-ray Science Division, APS
Materials Science, Chemistry, Environmental Science

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.

 

Supported Techniques

  • X-ray absorption fine structure

Beamline Controls and Data Acquisition

Sun UNIX running EPICS with VME, SPEC. PC/labview interface to EPICS.

Detectors

  • Ion chambers
  • Lytle detector
  • 4-element Vortex SDD detector on request
  • 13-element Ge solid state detector
  • electron yield detector

Additional Equipment

  • Cryostat (10-300 K) on request
  • Bruker FTIR spectrometer (concurrent DRIFTS and XAFS)
  • Automated hazardous gas handling
  • Mass spectrometer
  • Variety of in-situ cells for catalysts, liquids and batteries
  • Glove box (nitrogen, 0.1 ppm O2, 0.7 ppm water) for sample prep
