Time-resolved science has a high priority at DESY and in the institutions present at the Campus Bahrenfeld, including institutes of the Universität Hamburg. This interest is fueled by the short pulse facilities available in close vicinity, in particular the Free Electron Lasers, FLASH and the European XFEL. These lightsources enable measurements of ultrafast phenomena on timescales as short as 10s of femtoseconds. However, time-resolved experiments are also performed at the PETRA III synchrotron with a temporal resolution of the X-ray pulse duration of 100 picosecond, i.e., a timescale characteristic for structural dynamics in solids, nanostructures and macromolecules. In a series of invited and contributed talks, this PIER workshop presented a comprehensive overview of instruments and facilities for time-resolved experiments available at PETRA III.

The workshop interconnected users and scientists at various beamlines at PETRA III and at other lightsources in Hamburg. The program was divided into technical and scientific talks and addresses students, experienced researchers, beamline scientists and external users, of which around 30 people attended. The poster and discussion sessions provided opportunities for discussions of cooperation in science and methods development, e.g. active X-ray optics or fast time-resolved XRD experiments.
