Two lines: BM26A=XAFS  BM26B=SAXS/WAXS
 
The DUBBLE project operates two beam lines whose main techniques are time-resolved SAXS/WAXS and XAFS. The latter technique can also be performed in a time-resolved mode.

We offer flexibility and high quality data

Two Pilatus detectors are currently available for SAXS and WAXS measurements on the SAXS/WAXS beamline (see SaxsWaxs)

What research is performed here?

The SAXS/WAXS beam line is largely devoted to soft condensed matter research, although scientists from many other research fields (geology, mineralogy, metallurgy, etc.) are also regular visitors.

The XAFS beam line is specialised in on-line catalysis experiments but this is definitely not the only type of experiment carried out here.  Several complementary techniques can also be performed simultaneously with the EXAFS experiments.

  • team from Department of Mechanical Engineering, Eindhoven University of Technology, NL, characterise amorphous polystyrene under pressure on BM26B

  • simultaneous rheology and SAXS in an unusual vertical configuration on BM26B

 

The beam was deflected through 90 degrees upwards and the detector was mounted on the ceiling! In the photos the rheometer has not yet been installed. The X-rays passed right through the rheometer plates allowing us to collect excellent SAXS and rheology data. In addition it was possible to scan the rheometer across the beam enabling us to explore different shear rates.

These users were happy even before they collected their data!

 

  • in-situ shear-flow (MPR) cell combined with simultaneous SAXS/WAXS analysis

In the photo you can see the window into the WAXS detector (yellow kapton) together with the cone leading to the SAXS detector. The MPR allows you to vary shear and control temperature. Millisecond time resolution allowed these users to follow their polymer crystallisation process in detail.
