The lower energy diffraction and scattering side-bounce beamline for materials science at the Canadian Light Source

Abstract

A new diffraction beamline for materials science has been built at the Canadian Light Source synchrotron. The X-ray source is an in-vacuum wiggler with a 2.5 T peak magnetic field at 5.2 mm gap. The optical configuration includes a toroidal mirror, a single side-bounce Bragg monochromator, and a cylindrical mirror, producing a sub-150 µm vertical × 500 µm horizontal focused beam with a photon energy range of 7–22 keV and a flux of 1012 photons per second at the sample position. Three endstations are currently open to general users, and the techniques available include high-resolution powder diffraction, small molecule crystallography, X-ray reflectivity, in situ rapid thermal annealing, and SAXS/WAXS. The beamline design parameters, calculated and measured performance, and initial experimental results are presented to demonstrate the capabilities for materials science.

Multication perovskite 2D/3D interfaces form via progressive dimensional reduction

“…We next used in situ GIWAXS in order to gain insight into the formation of the 2D/3D interface. Measurements were performed at the Brockhouse Beamline 22 at the Canadian Light Source using a custom homebuilt spinning platform (see Supporting Information for details of the experimental setup and execution). In situ GIWAXS patterns for films of MAPbI 3 treated with a solution of 5 mg/mL VBABr in isopropanol (IPA) are shown in Fig.…”

Halogen- and hydrogen-bonded self-assembled fibrillar networks of substituted 1,3:2,4-dibenzylidene-d-sorbitols (DBS)

“…24 Additional powder diffraction data were collected on the DBS-Cl sample using the Brockhouse Wiggler Low Energy (WLE) beamline at CLS with λ = 0.82013 Å radiation and a Dectris Mythen2 X series 1K linear strip detector at a distance of 1128 mm. 25 The structures were analyzed using the GSAS-II and FOX software, 26 while density functional theory (DFT) optimization was done using CRYSTAL17 software. 27 Fourier transform infrared spectroscopy (FTIR)…”

High-repetition-rate seeded free-electron laser with direct-amplification of an external coherent laser

“…The pulse duration is 350 fs (FWHM). The modulator is an in-vacuum undulator with a 2.3 T peak magnetic field at 5.3 mm gap [55]. K parameter of the modulator is 17.5.…”
