The upgrade of beamline BL08U1A at SSRF has been recently conducted. The energy range is 180–2050 eV, the energy resolution can reach up to 16333 @ 244 eV and 12730 @ 401 eV, and the photon flux measured in the experimental station is over 2.45 × 109 photons s−1 (E/ΔE = 6440 @ 244 eV).
optics
At the German synchrotron radiation facility BESSY II, the VUV photon energy range between 15 and 600 eV is covered by the first, third and fifth harmonics of the U125 undulator. The beamline connected to this source is a plane-grating monochromator (PGM) with a variable deviation angle. The plane grating is illuminated by collimated radiation, allowing very flexible use of the monochromator. Depending on users' demands, it can be operated at high spectral resolution, high-order suppression or in high-flux mode, simply by software control.

The dynamical diffraction Talbot effect behind a crystal in free space is considered. The theoretical predictions of the effect are confirmed by numerical calculations.
PhotonMEADOW2023 workshop
A state-of-the-art multilayer deposition system has been developed at Diamond Light Source; this instrument is engineered to produce single and multilayer coatings, accommodating mirrors up to 2000 mm in length through the utilization of eight rectangular cathodes.

A new monochromator called an extra-focus constant-included-angle varied-line-spacing cylindrical-grating monochromator (extra-focus CIA-VCGM) is described. It is based on the Hettrick–Underwood scheme where the plane varied-line-spacing grating is replaced by a cylindrical one in order to zero the defocus at three reference photon energies in the VUV range.
research papers
A simple and complete one-dimensional wavefront propagation model for beamline analysis is developed in the WOFRY package in OASYS. It is used to analyze how the thermal load of the white-beam mirror degrades the wavefront. This can be corrected by an adaptive mirror, with some limitations that are studied.
research papers
The optimization of an efficient plane-grating monochromator for covering the entire soft X-ray range with photon energies up to about 8 keV is described. The instrument is based on the operation of a plane grating in conical diffraction, which can provide high efficiency over a large, and presently rather uncommon, tuning range for grating monochromators.

The design and performance test of the vacuum ultraviolet beamline BL03U at SSRF are described.

X-SPEC is a high-flux undulator beamline for electron and X-ray spectroscopy with an energy range from 70 eV to 15 keV. It offers X-ray absorption spectroscopy (XAS), extended X-ray absorption fine structure (EXAFS), photoelectron spectroscopy (PES) and hard X-ray PES (HAXPES), as well as X-ray emission spectroscopy (XES) and resonant inelastic X-ray scattering (RIXS) for in vacuo, in situ and operando sample environments.

BOREAS is a beamline operating at the ALBA Synchrotron Light Source, dedicated to resonant X-ray absorption and scattering experiments using soft X-rays, in an unusually extended photon energy range from 80 to >4000 eV, with full polarization control. Here its optical scheme and the first commissioning results are described.
