Since the discovery of strong spin-orbit coupled materials such as Rashba systems, topological insulators, and Weyl semimetals, spin- and angle-resolved photoemission spectroscopy (SARPES) has become a very important technique to investigate spin-dependent electronic structures. A combination of the electron analyzer with the state-of-the-art spin polarimeter based on a very low energy...

X-ray Absorption Fine Structure spectroscopy (XAFS) is crucial to investigate the electronic and atomic structure of different kinds of samples [1]. The efficacy of this technique, widely deployed at synchrotron facilities, is constrained by the performance limitations of the current generation of Ge detectors. To perform XAFS measurements,...
This work reports on the recent activities carried out by the Detector and Instrumentation Laboratory of Elettra Sincrotrone Trieste. Since both the Elettra synchrotron and the Fermi free electron laser are generating photons in the low to medium x-ray energy range from some eV to tenths of keV the activities of the detector and instrumentation laboratory focuses on spectroscopic and imaging...
A new experimental setup, which includes a highly photon sensitive spectrometer based
on superconducting transition edge sensors (TES) is under commissioning at BESSY II.
The setup is dedicated to XAS, XES and RIXS experiments in the soft X-ray regime with a
strong emphasis on the study of low concentration systems, which can be divided into two
main themes: 1) solids and low dimensional...
Hybrid detectors for hard X-rays developed at the Paul Scherrer Institute (PSI) have demonstrated outstanding performance in terms of fast frame rate, large dynamic range, large area, stability, reliability, and ease of use. To enable these features also for soft X-rays, two main limitations of state-of-the-art detectors have to be addressed: low quantum efficiency and low signal-to-noise...
At SSRL, we employ a transition-edge sensor (TES) spectrometer for soft X-ray spectroscopy, including XAS, XES, and RIXS. While offering a moderate energy resolution of ~1.5 eV FWHM, the TES excels in detection efficiency and broad spectral coverage. These strengths have proven valuable in tackling challenging samples, such as those susceptible to radiation damage and extremely dilute frozen...
The diagnostics of the X-ray beam properties has a critical importance at the European X-ray Free Electron Laser facility. Besides existing diagnostic components, utilization of a diamond sensor was proposed to achieve radiation-hard, non-invasive beam position and pulse energy measurements for hard X-rays [1]. In particular, at very hard X-rays diamond-based sensors become a useful complement...
