Spectroscopy: Beamline 9-BM


APS Beamline PlanviewThe 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.
