Prospects of High Resolution Resonant X-ray Inelastic Scattering Studies on Solid Materials, Liquids and Gases at Diffraction Limited Storage Rings

T. Schmitt, F. M. F. de Groot and J. Rubensson

Synopsis: Diffraction limited storage rings will allow for pushing the achievable energy resolution, signal intensity and the sampled spot size in Resonant Inelastic X-ray Scattering (RIXS) experiments to new limits. In this article we envision what kind of improved soft X-ray RIXS studies will become possible with these instrumental improvements.

The synchrotron X-ray-induced reduction of Au ions lead to the formation of Au nanoparticles on the carbon particles, acrylic cell or polyimide window. The deposited Au metallic spots were affected by the wettability of carbon particles.

K. Holldack, J. Bahrdt, A. Balzer, U. Bovensiepen, M. Brzhezinskaya, A. Erko, A. Eschenlohr, R. Follath, A. Firsov, W. Frentrup, L. Le Guyader, T. Kachel, P. Kuske, R. Mitzner, R. Müller, N. Pontius, T. Quast, I. Radu, J.-S. Schmidt, C. Schüßler-Langeheine, M. Sperling, C. Stamm, C. Trabant and A. Föhlisch

Synopsis: The layout and commissioning of the upgraded time-slicing facility FemtoSpeX at BESSY II is described. A new approach to femtoslicing based on a separated twin amplifier scheme linked by a single joint seed oscillator has been used. With a successful upgrade in repetition rate, the installation of a novel high-flux monochromator and a new background-suppression scheme based on hopping between different `camshaft' bunches, combined with a local orbit bump in the electron beam, the slicing efficiency, its stability and the laser performance are significantly enhanced. Owing to these considerable improvements, new methods in resonant diffraction and reflection are now feasible that pave the way for new exciting experiments in the field of ultrafast magnetism and phase transitions in solids.
