Design and performance of a dedicated coherent X-ray scanning diffraction instrument at beamline NanoMAX of MAX IV

Abstract

The diffraction endstation of the NanoMAX beamline is designed to provide high-flux coherent X-ray nano-beams for experiments requiring many degrees of freedom for sample and detector. The endstation is equipped with high-efficiency Kirkpatrick–Baez mirror focusing optics and a two-circle goniometer supporting a positioning and scanning device, designed to carry a compact sample environment. A robot is used as a detector arm. The endstation, in continued development, has been in user operation since summer 2017.

Investigating the Electromechanical Behavior of Unconventionally Ferroelectric Hf0.5Zr0.5O2‐Based Capacitors Through Operando Nanobeam X‐Ray Diffraction

“…In-Situ Biasing Burst Diffraction Experiment: The operando experiments were performed at the NanoMAX beamline of the MAX IV Laboratory in Lund, Sweden. [24] Following a synchronisation scheme developed elsewhere [25] beam of wavelength 1.379 Å and a beam size of 100 nm in diameter was used. A burst voltage scheme was used consisting of triangular pulses of 97 Hz frequency while acquiring X-ray images and current measurements at 1 kHz.…”

Chemical Limits on X-ray Nanobeam Studies in Water

“…All X-ray experiments were performed at the diffraction station of the NanoMAX beamline, MAX IV Laboratory. ,, The Pd/carbon sample was suspended in MilliQ water by sonication. For measurements in air, the sample was deposited on a Si 3 N 4 membrane by allowing a drop of the suspension to dry under an inert gas flow.…”

Nanoscale X-ray Imaging of Composition and Ferroelastic Domains in Heterostructured Perovskite Nanowires: Implications for Optoelectronic Devices

“…The nanowires were characterized with the hard X-ray nanoprobe NanoMAX , at the fourth-generation synchrotron source MAX IV Laboratory in Lund, Sweden. A schematic sketch of the experimental setup is shown in Figure d.…”

“…A Merlin Quad 2D pixel detector with 55 μm pixel size was placed on a robot arm in Bragg geometry at around 2θ = 17°, at a distance of 0.3000 m from the sample. The detector robot has an accuracy of 20 μm for absolute positioning precision and less than 10 μm for repeatability. , At a detector distance of 300 mm, this should give an inaccuracy of about 10 –4 . Note that this does not affect the relative strain variations since the detector position was held fixed during the measurements.…”
