abstract = {What is often well established at many synchrotron beam
lines is still in the development phase at neutron beam
lines: In-situ light scattering techniques. The science case
for in-situ light scattering at neutron instruments lies
mostly in the limited reproducibility of sample preparation
and stability of the samples over time. Whereas many soft
matter or hard matter samples are not transparent for light,
many biological samples often show a sufficiently broad
spectral range where light absorption does not play a
dominant role. Natural candidates for neutron instruments to
be equipped with in-situ light scattering techniques are
small angle scattering, spin echo, time-of-flight and
backscattering beam lines. We routinely supply in-situ
dynamic light scattering with one fixed scattering angle at
the instrument KWS-2 at MLZ to users who would like to
control their sample during the neutron measurement.
Recently, we have successfully tested a three angle dynamic
light scattering set-up at KWS-2. For the Jülich neutron
spin echo spectrometer we are currently developing a
prototype sample environment which includes two scattering
angles and a transmission detector. The transmission
detector reports on a change in turbidity with a very high
time resolution. This is especially attractive to
thermoresponsive soft matter samples with a very narrow
transition from a swollen to a more compact micellar state.},
