TL;DR: In this article, the authors developed different types of photodetectors that are based on the photoionization of a gas at a low target density for online photon diagnostics at current and future x-ray free-electron laser facilities.

TL;DR: The Metrology Light Source is a recently constructed 630 MeV electron storage ring, operating as a synchrotron radiation source for the THz to extreme UV spectral range as discussed by the authors.

TL;DR: Scanning near-field optical microscopy with a spatial resolution below 100 nm is demonstrated by using low intensity broadband synchrotron radiation in the IR regime to perform nano-Fourier-transform infrared spectroscopy over a wide spectral range.

TL;DR: The conclusions established in this study can be extended to a variety of transition metal trichalcogenide materials as well as other quasi-1D crystals, and the possibility of exfoliation of TiS3 into narrow crystals with smooth edges could be important for the future realization of miniature device channels with reduced edge scattering of charge carriers.

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.
