The newly constructed Debye beamline at the Swiss Light Source (SLS), available for users after the SLS upgrade mid-2025, is aiming at X-ray absorption spectroscopy and X-ray diffraction analysis to probe the chemical and electronic structure of functional materials under operating conditions. As part of the optical system, a new quick scanning channel-cut monochromator with its control system...
X-ray nanospectroscopy offers the capability to analyze various information such as elements and chemical states with high spatial resolution. Enhancing the sensitivity and spatial resolution requires the use of X-ray focusing optics. Among these optics, X-ray total-reflection mirrors are promising due to their high reflectivity, low chromatic aberration, and excellent radiation hardness....
Angle resolved photo-electron spectrometers with micro-channel plate detectors and combined with fast digitizer electronics are versatile and powerful devices for providing both soft and hard X-ray non-invasive single shot photon diagnostics at MHz repetition rate X-ray free-electron lasers.
Hard X-ray beamlines imposes specific design challenges due to poor photo-ionization cross-section and...
High Energy Photon Source (HEPS), the fourth-generation synchrotron radiation facility under construction in Beijing, is designed to operate at an electron energy of 6 GeV with an emittance lower than 60 pm·rad. The high-quality X-ray near diffraction limit presents unprecedented challenges for optical technology. This presentation will provide a comprehensive overview of the current state of...
The LCLS-II superconducting accelerator has begun operations and has produced x-rays since August 2024. The initial parameters are a photon energy range from 250 eV to 3.8 keV and a maximum repetition rate of 1 kHz. The absorption edges of solid filters were used to calibrate the photon energy and evaluate the FEL bandwidth from the hard x-ray undulator. The observed aluminum K absorption edge...
Full-field Transmission X-ray Microscopy (TXM) is a powerful imaging technique widely used in material, energy, and biological sciences. Synchrotron-based TXM systems offer exceptional spatial resolution in the tens of nanometers range, along with remarkable three-dimensional non-destructive nanoimaging capabilities. A crucial component in TXM setups is the condenser, which can be of different...
