TL;DR: In this paper, the advantages of synchrotron radiation in charge density studies of coordination complexes are described and illustrated with a number of recent synchoretron studies, ordered according to the atomic number of the metal atom involved (Cr, Fe, Cu, Zr, Mo, Th).

TL;DR: The Metrology Light Source (MLS) as discussed by the authors is the electron storage ring of the Physikalisch-Technische Bundesanstalt (PTB) located in Berlin and is dedicated to metrology and technological developments in the UV and extreme UV spectral range as well as in the IR and THz region.
Abstract: The Metrology Light Source (MLS), the new electron storage ring of the Physikalisch-Technische Bundesanstalt (PTB) located in Berlin, is dedicated to metrology and technological developments in the UV and extreme UV spectral range as well as in the IR and THz region. The MLS can be operated at any electron beam energy between 105 and 630 MeV and at electron beam currents varying from 1 pA (one stored electron) up to 200 mA. Moreover, it is optimized for the generation of coherent synchrotron radiation in the far IR/THz range. Of special interest for PTB is the operation of the MLS as a primary radiation source standard from the near IR up to the soft x-ray region. Therefore, the MLS is equipped with all the instrumentation necessary to measure the storage ring parameters and geometrical parameters needed for the calculation of the spectral photon flux according to the Schwinger theory with low uncertainty.

TL;DR: In this article, the authors proposed a model to explain the broadband optical to the X-ray spectra and the variability properties of the cross-correlation functions observed in three black hole binaries exhibited a complicated shape.
Abstract: The physical picture of the emission mechanisms operating in the X-ray binaries was put under question by the simultaneous optical/X-ray observations with high time resolution. The light curves of the two energy bands appeared to be connected and the cross-correlation functions observed in three black hole binaries exhibited a complicated shape. They show a dip of the optical emission a few seconds before the X-ray peak and the optical flare just after the X-ray peak. This behavior could not be explained in terms of standard optical emission candidates (e.g., emission from the cold accretion disk or a jet). We propose a novel model, which explains the broadband optical to the X-ray spectra and the variability properties. We suggest that the optical emission consists of two components: synchrotron radiation from the non-thermal electrons in the hot accretion flow and the emission produced by reprocessing of the X-rays in the outer part of the accretion disk. The first component is anti-correlated with the X-rays, while the second one is correlated, but delayed and smeared relative to the X-rays. The interplay of the components explains the complex shape of the cross-correlation function, the features in the optical power spectral density as well as the time lags.

TL;DR: The current best detection limit achieved at the Stanford Synchrotron Radiation Laboratory (SSRL) for Ni is 8×10 7 atoms/cm 2 which is a factor of 50 better than what can be achieved using laboratory-based sources as mentioned in this paper.
