abstract = {A temperature-controlled sample environment was developed
and verified for a Double Pulse Photon Correlation
Spectroscopy (DPPCS) setup. Various polystyrene and
ther-moresponsive Poly(N-Isopropyl Acrylamide) (pNipam)
samples were characterized in Dy-namic Light Scattering
(DLS) measurements. The thermoresponsive properties of the
pNipam sample were investigated in a Small Angle X-Ray
Scattering (SAXS) experimentat the beamline P10 of PETRA
III. At q≈0.005Å$^{−1}$, an increase in scattered
intensitywith increasing temperature was observed,
indicating volume (radius) transition of theparticles. To
verify the performance of the DPPCS setup in measuring
dynamics, thepolystyrene samples were used in Single Pulse
Photon Correlation Spectroscopy. Thefastest sample’s
radius was determined to R$_h$= 27±3nm, which agrees well
with thesize provided by the manufacturer (R= 25±4nm). The
pNipam sample was measured attemperatures fromT= 20°C to
50°C both with Single and Double Pulse Photon Correla-tion
Spectroscopy to verify the performance of the newly
developed temperature-control. Both measurements showed the
characteristic decrease of the radius at a transition
temperature of T≈32°C, demonstrating reliable
functionality of the temperature-controlledsample
