Lay Summary (English)

Lay summary
X-ray photoelectron diffraction (XPD) is a well-established technique for surface and near-surface structural investigations with a particularly strong Swiss community. Following the pioneering work of Osterwalder, Greber and Stuck at the University of Fribourg, it has been implemented in three different research laboratories in Switzerland: At the Universities of Zurich (Greber, Osterwalder) and Neuchatel (Aebi), and at the Swiss Federal Laboratories for Materials Testing and Research, Empa (Fasel, Gröning). During the last few years, XPD has intensively and successfully been applied to a wide variety of systems in the context of various scientific problems in all three laboratories. Since the year 2001, it has furthermore been possible to explore the potential of synchrotron-radiation XPD (SR-XPD) at the Near Node PhotoElectron Holography end-station (NNPEH) set-up by Greber at the Surface and Interface Microscopy (SIM) beamline of the Swiss Light Source (SLS). Thanks to the high brilliance of the SLS and the possibility of choosing the 'correct' photon energy for a particular experiment, the scope of XPD could be extended to systems and scientific prob-lems not previously accessible by any other experimental technique.Given the success of the last few years' SR-XPD "pilot-phase" using the (basic) NNPEH endstation at the SLS, the established need for complementary SR-XPD experiments in various fields of research, the strong Swiss XPD community, as well as the many researchers that have expressed their interest in SR-XPD ex-periments, we propose the planning and construction of a dedicated endstation for SR-XPD: PEARL - a PhotoElectron Diffraction and Atomic Resolution Laboratory at the SLS. It is our aim and ambition to develop a dedicated endstation for state-of-the-art angle- and energy-scanned XPD, combined with normal-incidence x-ray standing wavefield absorption (NIXSW) and Scanning Tunneling Microscopy (STM) characterisation. PEARL shall also provide a means for developing next-generation XPD techniques including time- and spin-resolution, and to access experiments at low temperatures. PEARL will become a unique facility, unlike any other endstation world wide, and set-up, supported and further developed by a strong Swiss community of experts.
