abstract = {Low-dose X-ray photon correlation spectroscopy experiments
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.},
