A typical neutron scattering experiment lasts around four hours over which the sample might degrade and consequently produce wrong results. A team of researchers is working on a set up to control the sample quality along time so that false data can be discarded. This work will considerably improve the quality of neutron scattering data. One of the tasks of the NMI3’s Joint Research Activity on Advanced Neutron Tools for Soft and Bio-Materials is to design and build an in situ Dynamic Light Scattering (DLS) setup combined with neutron scattering to better control the sample quality over time. A prototype has now been built for the instrument KWS-2 of the Jülich Centre for Neutron Science at the Heinz Maier-Leibnitz Zentrum (MLZ) in Garching, Germany. This work is progressing very well. The team has shown that it is possible to mount and align a DLS setup on the neutron scattering instrument in less than 45 minutes. They have already tested the setup during an experiment and as desired it has provided valuable information on the sample stability and additional aggregates present. In this video, Tobias Schrader from JCNS and Raimund Heigl from the Technical University of Munich explain us their work.
