The XFM beamline at the Australian Synchrotron

The X-ray fluorescence microscopy (XFM) beamline is an in-vacuum undulator-based X-ray fluorescence (XRF) microprobe beamline on the three GeV Australian Synchrotron. The beamline delivers exhausting X-rays within the 4-27 keV power vary, allowing Ok emission to Cd and L and M emission for all different heavier parts. With a sensible low-energy detection cut-off of roughly 1.5 keV, low-Z detection is constrained to Si, with Al detectable beneath beneficial circumstances.

The beamline has two scanning stations: a Kirkpatrick-Baez mirror microprobe, which produces a focal spot of two µm × 2 µm FWHM, and a large-area scanning `milliprobe’, which has the beam measurement outlined by slits. Vitality-dispersive detector methods embody the Maia 384, Vortex-EM and Vortex-ME3 for XRF measurement, and the EIGER2 X 1 Mpixel array detector for scanning X-ray diffraction microscopy measurements.

The beamline makes use of event-mode information acquisition that eliminates detector system time overheads, and movement management overheads are considerably decreased by way of the appliance of an environment friendly raster scanning algorithm. The minimal overheads, along side quick dwell occasions per pixel, have allowed XFM to determine strategies reminiscent of full spectroscopic XANES fluorescence imaging, XRF tomography, fly scanning ptychography and high-definition XRF imaging over massive areas. XFM gives numerous evaluation capabilities within the fields of drugs, biology, geology, supplies science and cultural heritage. This paper discusses the beamline standing, scientific showcases and future upgrades.

Multiscale pink-beam microCT imaging on the ESRF-ID17 biomedical beamline

Latest traits in exhausting X-ray micro-computed tomography (microCT) goal at growing each spatial and temporal resolutions. These challenges require intense photon beams. Filtered synchrotron radiation beams, additionally known as `pink beams’, that are emitted by wigglers or bending magnets, meet this want, owing to their broad power vary. On this work, the brand new microCT station put in on the biomedical beamline ID17 of the European Synchrotron is described and an outline of the preliminary outcomes obtained for various biomedical-imaging functions is given.

This new instrument expands the capabilities of the beamline in direction of sub-micrometre voxel measurement scale and simultaneous multi-resolution imaging. The present setup permits the acquisition of tomographic datasets a couple of order of magnitude sooner than with a monochromatic beam configuration.

Growth of SPACE-II for fast pattern change at SPring-Eight macromolecular crystallography beamlines.

Decreasing the sample-exchange time is an important subject in maximizing the throughput of macromolecular crystallography (MX) beamlines as a result of the diffraction information assortment itself is accomplished inside a minute within the period of pixel-array detectors. To this finish, an upgraded pattern changer, SPACE-II, has been developed on the idea of the earlier mannequin, SPACE (SPring-Eight Exact Automated Cryo-sample Exchanger), on the BL41XU beamline at SPring-8. SPACE-II achieves one sample-exchange step inside 16 s, of which its motion accounts for under 11 s, due to three options: (i) the implementation of dual arms that allow samples to be exchanged in a single cycle of mount-arm motion, (ii) the implementation of long-stroke mount arms that enable samples to be exchanged with out withdrawal of the detector and (iii) the usage of a fast-moving translation and rotation stage for the mount arms.

By pre-holding the subsequent pattern previous to the sample-exchange sequence, the time was additional decreased to 11 s within the case of automated information assortment, of which the motion of SPACE-II accounted for Eight s. Furthermore, the pattern capability was expanded from 4 to eight Uni-Pucks. The efficiency of SPACE-II has been demonstrated in over two years of operation at BL41XU; the typical variety of samples mounted on the diffractometer in sooner or later was elevated from 132 to 185, with an error price of 0.089%, which counted incidents by which customers couldn’t proceed with an experiment with out restoration work by coming into the experimental hutch. On the idea of those outcomes, SPACE-II has been put in at three different MX beamlines at SPring-Eight as of July 2019. The quick and extremely dependable SPACE-II is now one of the vital essential items of infrastructure for the MX beamlines at SPring-8, offering customers with the chance to totally make use of restricted beamtime with good X-rays.

Cinema:Bandit: a visualization software for beamline science demonstrated on XFEL shock physics experiments.

A brand new visualization device, Cinema:Bandit, and its demonstration with a steady workflow for analyzing shock physics experiments and visually exploring the info in actual time at X-ray gentle sources is offered. Cinema:Bandit is an open-source, web-based visualization software by which the experimenter could discover an aggregated dataset to tell real-time beamline choices and allow publish hoc information evaluation.

The device integrates with experimental workflows that course of uncooked detector information right into a easy database format, and it permits visualization of disparate information varieties, together with experimental parameters, line graphs, and pictures.

Use of parallel coordinates accommodates the irregular sampling of experimental parameters and permits for show and filtering of each experimental inputs and measurements. The device is demonstrated on a dataset of shock-compressed titanium collected on the Matter in Excessive Circumstances hutch on the Linac Coherent Mild Supply.
