      abstract     = {A new sample environment, called Bio-Oven, has been built
                      for the Neutron Spin Echo (NSE) SpectrometerJ-NSE Phoenix.
                      It provides active temperature control and the possibility
                      to perform Dynamic Light Scattering(DLS) measurements during
                      the neutron measurement. DLS provides diffusion coefficients
                      of the dissolvednanoparticles and thus one can monitor the
                      aggregation state of the sample on a time scale of minutes
                      duringthe spin echo measurement times on the order of days.
                      This approach helps to validate the NSE data or toreplace
                      the sample when its aggregation state influences the spin
                      echo measurement results. The new Bio-Ovenis an in situ DLS
                      setup based on optical fibers decoupling the free space
                      optics around the sample cuvettein a lightproof casing from
                      the laser sources and the detectors. It collects light from
                      three scattering anglessimultaneously. Six different values
                      of momentum transfer can be accessed by switching between
                      two differentlaser colors. Test experiments were performed
                      with silica nanoparticles with diameters ranging from 20 nm
                      upto 300 nm. Their hydrodynamic radii were determined from
                      DLS measurements and compared with the onesobtained by a
                      commercial particle sizer. It was demonstrated that also the
                      static light scattering signal can beprocessed and gives
                      meaningful results. The protein sample apomyoglobin was used
                      for a long-term test and ina first neutron measurement using
                      the new Bio-Oven. The results prove that the aggregation
                      state of the samplecan be followed using in situ DLS along
                      with the neutron measurement.},
