MANATI (Micro-ANd SpectrAl Tomography Imaging) beamline will be primarily dedicated to X-ray tomography experiments at the micrometer scale, with a focus on fast and spectral (multi-energy) tomography techniques. Its objective is to provide high-resolution three-dimensional imaging combined with high-speed data acquisition and energy-based contrast, supporting applications in areas such as the energy transition, cultural heritage, advanced materials, and geosciences. In its initial configuration, MANATI will use a broad-spectrum X-ray beam with energies ranging from 20 to 80 keV. The spatial and spectral resolutions will be determined by the installed detector system, ranging from 1 to 20 µm.
