The purpose of the workshop is to explore the science case for developing and operating a next-generation compact coherent x-ray source in Sweden. The unique high repetition rate x-ray pulse pattern of the source will enable researchers to address novel scientific problems for atoms, molecules and condensed matter based on x-ray photoelectron spectroscopy and x-ray scattering techniques.
These sources bridge the gap between large-scale facilities such as MAX IV and the European XFEL and femtosecond laser systems as they are for instance used at Uppsala University’s HELIOS facility. Compact x-ray sources are based on a radically new approach replacing undulators with laser-based x-ray generation from relativistic electron beams. Worldwide, several sources of this type are planned or are under construction. We consider it important for Swedish science and technology to explore the benefits offered by this approach. In particular, we believe that superconducting accelerator technology available at Uppsala University will provide a head start to move such a development towards very high repetition rates.
The workshop aims at bringing together international experts in compact x-ray source development and photon science researchers who could use such facilities.
