The fourth-generation Brazilian Synchrotron Light Laboratory (LNLS/Sirius, CNPEM, Brazil) delivers low- to high-energy X-rays with high photon flux, enabling fast high-resolution 3D tomography. The MOGNO beamline [1] at the Sirius/LNLS provides nano- to micrometer-scale computed tomography, including multiscale and zoom tomography with ~200 nm resolution, as well as 4D in situ imaging with time resolution of a few seconds. Designed for flexible sample environments, MOGNO operates at 22, 39, and 67 keV and supports research in materials and energy sciences, including studies of rocks and porous media relevant to the oil industry and CO₂ storage. Current efforts focus on integrating micro-tomography with complementary techniques to investigate pore-scale transport and fluid–surface interactions. Nuclear Magnetic Resonance (NMR) provides fluid characterization and morphological information such as pore-size distribution, connectivity, wettability, and magnetic surface relaxivity [2]. Integrating zoom tomography with NMR offers an important approach to study porous media under static and dynamic conditions. In this talk, we discuss synchrotron-based simulations of NMR signals and the development of an NMR system, in partnership with FIT (Fine Instrument Technology - Brazil) [3], for in situ experiments at the MOGNO beamline.
