Towards chemically neutral carbon cleaning processes: plasma cleaning of Ni, Rh and Al reflective optical coatings and thin Al filters for free-electron lasers and synchrotron beamline applications

A chemically neutral low-pressure RF plasma cleaning technique for Ni, Rh and Al reflective coatings is presented. The successful carbon contamination cleaning of thin Al filters (100 nm thickness) for FEL and EUV applications is also demonstrated.

In situ observation of phase changes of a silica-supported cobalt catalyst for the Fischer–Tropsch process by the development of a synchrotron-compatible in situ/operando powder X-ray diffraction cell

An in situ catalysis powder X-ray diffraction cell compatible with scattering beamlines at the Stanford Synchrotron Radiation Lightsource has been designed, fabricated and tested. The experimental cell's performance was tested by the characterization of a silica-supported Co catalyst for Fischer–Tropsch synthesis and demonstrated that metallic Co can be carburized at a faster rate at 20 bar compared with at ambient pressure.

Ultra-small-angle X-ray photon correlation spectroscopy using the Eiger detector

The performance of the high-resolution fast-photon-counting Eiger 500k detector for sub-millisecond X-ray photon correlation spectroscopy measurement is demonstrated.

Accepted 29 September 2018

Subpixel resolution in CdTe Timepix3 pixel detectors

Using the Timepix3 ASIC ability to detect photons one-by-one, it is possible to take advantage of the charge-sharing effect to achieve subpixel positioning of single-photon events. A Timepix3 pixel (55 µm × 55 µm) was found to be sensitive to pencil beam (5 µm × 5 µm) steps of 5 µm. For a sample size of 1000 photons, the best result is achieved at 120 keV, where a beam step of 4.4 µm ± 0.86 µm was measured.

The extension of the wave zone of synchrotron radiation is studied.

Three-dimensional characterization of the microstructure in rabbit patella–patellar tendon interface using propagation phase-contrast synchrotron radiation microtomography

The first characterization of the three-dimensional microstructure in rabbit patella–patellar tendon interface using propagation phase-contrast synchrotron radiation micro-computed tomography is presented.

Towards synchrotron phase-contrast lung imaging in patients – a proof-of-concept study on porcine lungs in a human-scale chest phantom

This proof-of-concept study on a human-scale chest phantom and fresh porcine lungs with artificial pulmonary nodules demonstrates that local-area in-line free propagation phase-contrast synchrotron tomography of fresh porcine lungs can be performed with an acceptable X-ray dose that would allow for future application in patients while providing spatial-resolution magnitudes higher than currently available clinical computed tomography scanners.

Accepted 19 September 2018

Laser-heating system for high-pressure X-ray diffraction at the Extreme Conditions beamline I15 at Diamond Light Source

A double-sided, off-axis laser-heating system for monochromatic X-ray diffraction experiments using a diamond anvil cell has been installed at beamline I15 at Diamond Light Source. Measurements of the pressure–temperature phase diagram of Pb demonstrate the reliability of the setup and the high quality of the data.

Accepted 18 September 2018

Phospho­rus K-edge XANES spectroscopy has probably often underestimated iron oxyhydroxide-bound P in soils

Fe-bound soil Phosphorus (P) is probably often underestimated by LCF (linear combination fitting) conducted on P K-edge X-ray absorption near-edge structure (XANES) spectra, unless inositol hexaphosphate (IHP) adsorbed to ferrihydrite and IHP adsorbed to goethite are included as reference compounds.

A new reactor cell and experimental setup designed to perform time-resolved experiments on heterogeneous catalysts under working conditions that simulltaneously combines XAS, DRIFT and MS spectroscopies are reported.

Ultralow-temperature device dedicated to soft X-ray magnetic circular dichroism experiments

A new ultralow-temperature setup dedicated to soft X-ray absorption spectroscopy and X-ray magnetic circular dichroism experiments is described. Two experiments, performed on the DEIMOS beamline (SOLEIL synchrotron), demonstrate the outstanding performances of this new platform, particularly with regard to the lowest achievable temperature under X-ray irradiation (T = 220 mK).

Phenomenological and numerical analysis of power evolution and bunching in single-pass X-ray FELs

The power and bunching in a two-frequency undulator are studied analytically and numerically and compared with experiment. Based on the experimentally verified model, the two-frequency free-electron laser (FEL) is proposed with a dominant fifth harmonic at 0.15 nm, for which radiation reaches full power, ∼14 GW, at just 30 m, i.e. half the length of a FEL with a conventional undulator.
