Description
The Coherent Diffraction Imaging (CoDI) beamline is under development as part of the ALBA II upgrade to provide a dedicated platform for high-throughput, multimodal in situ and operando nanotomography. Exploiting the increased coherent flux and brightness of ALBA II, CoDI will operate over an energy range of 4–25 keV and is designed for samples up to approximately 500 µm in size, enabling investigations of materials and dynamic processes with nanometre spatial and minute-scale temporal resolution under representative operating conditions.
The beamline is centred on three complementary imaging modalities: ptychographic X-ray computed tomography (PXCT) for quantitative high-resolution 3D imaging, holotomography (HT) for rapid full-field volumetric imaging, and Bragg CDI/ptychography for three-dimensional strain and defect mapping. Future capabilities will include correlative X-ray fluorescence (XRF), diffraction (XRD), and X-ray spectromicroscopy (XANES, XMCD, XMLD), together with flexible sample environments and automated data-processing pipelines enabling near-real-time reconstruction. By combining complementary contrast mechanisms within a single experimental framework, CoDI will enable correlation of three-dimensional morphology, chemistry, crystallography, and electronic and magnetic properties during dynamic processes in functional and environmental materials.
