The DUBBLE project operates two beam lines. Mainly for 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 uses a large proportion of the time for soft condensed matter research although users of many other research fields, like 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 experiments that are carried out here.  Several complementary techniques can be performed simultaneously with the EXAFS experiments.

News from DUBBLE

In the 2009/2010 winter shutdown the sample preparation lab on the beam line has been merged with the former data analysis room and new equipment has been installed. This has been done in anticipation of the demolishing of the DUBBLE office/workshop block in the framework of the ESRF upgrade.

Light sample preparation work for BM26A and BM26B can be performed here. However, the new space can not be used anymore as office/desk space.

On the EXAFS beam line a new high pressure gas system has been installed. Mass flow meters suitable for a large variety of gasses and a large flow range have been installed in order to provide realistic catalytic conditions. Groups from Utrecht and Eindhoven University, as well as from the Dutch Energy Centre (Petten) have contributed their expertise and have contributed to the costs.

The Pilatus300K-W WAXS detector system will be installed in the March 2010 shutdown. The detector has been delivered and the required mechanical parts are being fabricated at the moment.
