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.
Synopsis: The magnet design of the MAX IV 3 GeV storage ring replaces the conventional support girder + discrete magnets scheme of previous third-generation light sources with a compact integrated design having several consecutive magnet elements precision-machined out of a common solid iron block.
Synopsis: Developments of optics for coherent X-ray applications and their role in diffraction-limited storage rings are described.
Synopsis: X-ray scanning microscopy greatly benefits from a reduced emittance of synchrotron radiation sources, especially from a diffraction-limited storage ring. Nanofocusing is discussed in view of focus size, flux and coherence.
Synopsis: A comprehensive review of some of the challenges encountered by the ESRF in the context of the preparation of the Phase II of its upgrade programme is presented.
Synopsis: The foreseen increase in coherent flux provided by diffraction-limited storage rings will allow ptychography to reach unprecedented throughput while retaining its inherently quantitative nature and metrological versatility.
Synopsis: The emerging opportunities for X-ray spectroscopy-based studies of working catalysts at diffraction-limited storage ring sources are discussed. The high photon flux of nanometer-size beams will enable electronic, structural and dynamic investigations of single catalytic particles in space and time domains.
Synopsis: A demostration of the computer program MANTiS (for Multivariate ANalysis Tool for Spectromicroscopy) for analysis of X-ray spectromicroscopy data is presented.
Synopsis: A collaborative framework for the analysis of synchrotron tomographic data which has the potential to unify the effort of different facilities and beamlines performing similar tasks is described. The proposed Python-based framework is open-source, platform- and data-format-independent, has multiprocessing capability and supports functional programming that many researchers prefer.
Synopsis: The radiation chemical analysis of X-ray-induced contrast enhancement in soft X-ray microscopy of hawk moth eye tissue shows that pre-illumination can foster biological X-ray imaging and gives insight into various radiation-induced decomposition pathways with high relevance for X-ray microspectroscopy.
Synopsis: A new principal-component-analysis-based method to extract the number of meaningful pure component XAFS spectra from unresolved multicomponent mixture spectra is presented. On both real and simulated mixtures it is shown that the new method is robust and outperforms the traditional forms of principal-component-analysis-based component-number estimation. A graphical data-analysis tool is provided for download.
Synopsis: A Ronchi interferometer for hard X-rays was used to characterize the performance of nanofocusing optics and beamline stability. The interferometer proved capable of obtaining qualitative data on optics aberrations, beamline spatial coherence, and pin-point vibrations and drift of beamline components.
Synopsis: Possible future directions for high-pressure science on fourth-generation storage rings are presented.
Synopsis: In situ time-resolved XANES measurements of Au ions in an aqueous solution in the presence of support materials were performed under synchrotron X-ray irradiation. 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.
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.
Synopsis: The lattice design and beam dynamics optimization for Sirius, a new low-emittance synchrotron light source presently under construction at the Brazilian Synchrotron Light Laboratory (LNLS) in Campinas, Brazil, is presented.
Synopsis: The design of the MAX IV 3 GeV ultralow-emittance storage ring is presented and the implementation of solutions to the technological challenges imposed by the compact multi-bend achromat lattice are described.
Synopsis: The design and plans for implementing fourth-generation and diffraction-limited storage rings around the world are discussed.
Synopsis: Approaches to generating short X-ray pulses with storage rings are discussed, with emphasis on the methods of using superconducting harmonic cavities and injecting short bunches for multi-turn circulation.
Synopsis: A compact lattice and small magnet apertures will be the main characteristics of future diffraction-limited storage rings, adding difficulties for the design of the vacuum system of these machines. The use of NEG coatings and distributed absorbers could provide a solution to overcome these challenges.
