Accelerator based light sources like synchrotron radiation and Free-Electron-Laser (FEL) facilities have developed into indispensable analytical tools for modern science. They are capable of provide extremely intense and collimated beams of photons extending from the visible to the hardest X-ray regime. These facilities are used by scientist from many fields of science ranging from physics, chemistry, biology, medicine, materials, earth and environmental sciences, and various disciplines of engineering to cultural heritage. Meanwhile, a number ofscience fields depend completely on the availability of the analytical capabilities of these sources and the facilities in Germany alone welcome more than 10000 user visits per year with this number steadily increasing. During the last years accelerator based light sources have gone through a revolutionary phase. The extremely short and intense X-ray pulses of the recently established FELs allow for the investigation of the dynamic properties of matter at atomic length and time scales and thus opening a totally new observation window into matter at the nano and atomic scale. However, also in the field of storage ring-based sources a disruptive revolution is ongoing through the ongoing development of new magnetic storage ring lattices allowing for electron beams of very low emittance and, therefore, extremely bril-liant beam that can efficiently be focused down to the 10 nm scale for the spatial resolved investigation of any kind of matter on this length scale. This seminar will address the scientific opportunities opened by modern accelerator based light sources as well as the technical issues both on the side of the accelerators and of the experiments in order to develop this field even further.
The conference language will be English. The Wilhelm and Else Heraeus-Foundation bears the cost of full-board accommodation for all participants.
