Brockhouse X-ray Diffraction and Scattering Beamlines - Undulator Beamline

Overview

Brockhouse is a suite of 3 beamlines dedicated to using hard X-rays for diffraction and scattering techniques for material science. Two beamlines have a wiggler source and the third beamline has an undulator source. Brockhouse offers a wide range of complementary techniques for structural characterization, including high resolution powder diffraction, small molecule crystallography, total scattering to produce the pair distribution function, micro-single crystal diffraction, high pressure setups, anomalous/magnetic diffraction, low angle X-ray reflectivity, grazing incidence diffraction, and inelastic scattering. There is also a highly specialized station from IBM that allows diffraction experiments with temperature control up to 1100°C, ultra-high pure N2 or He atmospheres, and in-situ roughness and resistance probes for the characterization of thin films.

The undulator beamline specializes in single crystal and thin film structural characterization.
