MODERNISATION PROGRAMMES AND TECHNICAL DEVELOPMENTS

In our pilot study, we demonstrated the feasibility of studying dynamic water transfer in root-soil systems
by high-speed neutron tomography. With a 1.5 s acquisition time per tomogram, we have set a new benchmark for time-resolved neutron tomography. This record demonstrates most impressively the potential of the instrument NeXT, pointing to many further applications in the fields of soil, materials and geosciences.
