xcalib: a focal spot calibrator for intense X-ray free-electron laser pulses based on the charge state distributions of light atoms

The xcalib toolkit has been developed to calibrate the spatial fluence distribution at the focal spot of an intense X-ray free-electron laser beam. The method is based on an automated optimization procedure that compares experimental charge state distributions with first-principles calculations.

Commissioning of a photoelectron spectrometer for soft X-ray photon diagnostics at European XFEL

The paper describes commissioning and first operation of an angle resolved Photoelectron Spectrometer for non-invasive shot-to-shot diagnostics for photon energy and polarization at the European XFEL soft X-ray beamline SASE3.

A convolutional neural network for fast upsampling of undersampled tomograms in X-ray CT time-series using a representative highly sampled tomogram

A convolutional neural network has been designed to quickly and accurately upscale the sinograms of X-ray tomograms captured with a low number of projections, effectively increasing the number of projections. This is particularly useful for tomograms that are part of a time-series as, in order to capture fast-occurring temporal events, tomograms have to be collected quickly, requiring a low number of projections. The upscaling process is facilitated using a single tomogram with a high number of projections for training, which is usually captured at the end or the beginning of the time-series when capturing the tomogram quickly is no longer needed.

Wavefront-propagation simulations supporting the design of a time-delay compensating monochromator beamline at FLASH2

Accepted 9 March 2019

Characterizing transmissive diamond gratings as beam splitters for the hard X-ray single-shot spectrometer of the European XFEL

Grating structures with 150 nm pitches were fabricated on free-standing CVD diamond membranes supported by a silicon frame. The efficiencies and structural homogeneity of the gratings were measured with synchrotron X-rays at different photon energies.

Accepted 20 February 2019

Probing the spatial coherence of wide X-ray beams with Fresnel mirrors at BL25SU of SPring-8

A Fresnel-mirror-based optical system was constructed to determine the degree of spatial coherence at the soft X-ray beamline of SPring-8. The spatial coherence properties in the horizontal and vertical directions were measured with a transverse range of larger than 1 mm.

Accepted 18 February 2019

Nature of cobalt species during the in situ sulfurization of Co(Ni)Mo/Al2O3 hydro­desulfurization catalysts

From 1s X-ray absorption and 1s3p resonant inelastic X-ray scattering, the valence, coordination and symmetry of cobalt ions were tracked in two cobalt-promoted molybdenum oxide precursors of the hydro­desulfurization catalyst system.

Accepted 11 February 2019

Pump–probe experimental methodology at the Linac Coherent Light Source

Techniques developed at LCLS to make optical laser pump–X-ray probe experiments both robust and easy to implement at ultrafast X-ray free-electron lasers are presented.
