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 6-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.

Beam Line Specifications


33-pole, 1.27-Tesla wiggler, 1.5 mrad acceptance

  Energy Range Resolution ΔE/E Spot Size Flux Angular Acceptance
Focused 5000-22000 eV ~1 x 10-4 0.30mm x 0.6mm ~ 3 x 1012 1.5 mrad



M0 mirror: vertically and horizontally focusing Rh coated bent cylinder 1.2 m long.

Monochromator: Si(111) and Si(220), double-crystal, non-fixed exit.


508 μm Be, 4.4 m He, 205 μm fixed, 1016 μm graphite (insertable, user controlled)


Detectors: Single element Vortex detector(s), ionization chambers. Pilatus 100K and 300K by arrangement with beam line engineer.

Rear hutch: Huber 6-circle diffractometer for high-resolution x-ray scattering research. Sixdiffractometermeter degrees of freedom are (q, χ, ϕ) for the sample, and (2-q, q-analyzer, 2-q-analyzer) for the detector.  Typical programs involve intrinsically weak scattering systems, such as two-dimensional arrays and high-resolution 3-D problems.

Other: variable filters to alleviate beam damage.
