                      on biological samples can be used to investigate the
                      structure formation and underlying dynamics during phase
                      separation, denaturation, and gelation. However, the use of
                      intensive X-ray beams as an investigative tool is limited
                      due to the susceptibility of biological samples to
                      radiation-induced changes. XPCS in particular requires
                      recording a series of high-frame-rate images to capture fast
                      dynamics. In such cases, a fast X-ray shutter system is
                      required to minimize beam damage to the samples by allowing
                      a flexible delay between two images. Here we show how a fast
                      (250 Hz) X-ray shutter system, built by the University of
                      Siegen in close collaboration with DESY, improves low-dose
                      XPCS capabilities at the P10 beamline at PETRA III. We found
                      that by employing this shutter system in a logarithmic
                      sampling scheme, the absorbed X-ray dose on the samples
                      could be significantly decreased.},
