The IHEP will break ground on an ultralow emittance synchrotron (tentatively named as High Energy Photon Source or HEPS) in Beijing in late 2018. The HEPS is a greenfield next generation synchrotron with ~50 pm.rad emittance, 6 GeV energy and 1360 m ring. In its Phase I, we will build a 200 m long Structural Dynamics Beamline (SDB). The SDB will focus on structural evolution in irreversible processes captured by ultrafast X-ray probes, especially for those processes related to dynamic compression and additive manufacturing. The goal of this workshop is to bring together leading experts in both beamline/instrumentation and applications in order to envision science cases for SDB as the beamline will be not operational until 2025, and to make sure that the SDB take full advantage of high coherence, high brigtnees and high energy (>20keV) X-ray originated from the ultralow emittance HEPS. We will discuss the optimization of the beamline, including undulators, beamline optics, diagnostics, detectors as well as the advancement of the fast X-ray probes, like imaging, diffraction, scattering and spectroscopy and emerging coherent X-ray methods. The technical aspects of the HEPS and the SDB will be introduced, and the SDB design, including the beamline and instrumentations, will be critically reviewed within the context of its scientific applications.
