Experimental Station 10-2b

Beam line 10-2 is a wiggler end-station that splits time between the back hutch (BL10-2b), which is instrumented for x-ray absorption spectroscopy, and the front hutch (BL10-2a), which has a dedicated 2-circle diffractometer that is used for materials scattering. The beamline supports the use of multiple area detectors, as well as point detectors with a crystal analyzer for higher angular resolution.
