Two Pilatus detectors are currently available for
SAXS and WAXS measurements on the SAXS/WAXS
beamline (see the News below and page SaxsWaxs)
The DUBBLE project operates two beam lines. We mainly cater to researchers in the remit of the Dutch and Flemish research councils but 30% of the beam time is available for general ESRF users. The main techniques are time-resolved SAXS/WAXS and EXAFS. The latter technique can also be performed in a time-resolved mode.
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 EXAFS 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.
News from DUBBLE
- 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.
