Rigaku Small Angle X-ray Scattering

FOM Name:  Rigaku SAXS
Model:  Rigaku
Contact:  Don Savage (dsavage@wisc.edu, 608-263-0831)
Center:  NIAC
Location: ERB Rm 832

The Rigaku SAXS has a Cu kx-ray source and operates at 40W.  In the highest resolution configuration the minimum angle measured is 5.8 x 10 –4 radians.  A Linkam heating/cooling stage is available with a temperature range of -50C to 300C with 0.5C degree precision.

Examples of materials analyzed with SAXS include polymers, biomaterials, fibers, colloids, metals and liquid crystals.
