      abstract     = {Understanding the dynamic and structural properties of
                      matter across different timescales and length scales is
                      essential for elucidating their functionality. We focus here
                      on soft-matter systems, which are typically particularly
                      sensitive to relative humidity (RH) and temperature,
                      necessitating well controlled experimental conditions.
                      Quasi-elastic neutron scattering (QENS) and Raman
                      spectroscopy offer complementary insights: QENS accesses
                      diffusional dynamics, which are stochastic motions, while
                      Raman spectroscopy provides information on periodic
                      vibrational dynamics. To enable simultaneous QENS and Raman
                      measurements on e.g. polymer films under controlled and
                      variable RH and temperature, we have developed a dedicated
                      sample environment (SE), which in the presented experiments
                      covers an RH range of $5–85\%$ and a temperature range of
                      20–50°C. This SE features a 3D-printed spherical chamber
                      including a sample holder for films, a Raman spectrometer, a
                      custom-built gas-flow system and a thermostat. The chamber
                      can accommodate large samples (up to 5 × 5 cm) and
                      provides space for additional measurement equipment. The
                      3D-printing technique allows the integration of channels
                      into the chamber walls, which are used for cooling and
                      heating, resulting in highly homogeneous temperature
                      distributions. This is key to achieving a uniform humidity
                      in the chamber. The chamber works with a variety of solvents
                      and their mixtures, like heavy water or ethanol. We
                      demonstrate the feasibility of this setup through
                      simultaneous QENS and Raman measurements on
                      poly(3,4-ethylene
                      di­oxy­thio­phene):poly(styrene­sulfonate) films on Si
                      substrates, confirming that the chamber provides a stable
                      and low scattering background environment.},
