We will determine whether a neutron technique called dark field Lamor imaging can provide quantitative information about the spatial distribution of small inhomogeneities in materials. Future applications might include studies of inaccessible pores in oil-bearing rocks, jamming in the flow of particulates (such as grain in silos), extrusion of polymer blends during manufacture, desirable or undesirable particle segregation or aggregation in additive manufacturing (3d printing) etc. In all of these cases neutrons may have advantages over other radiographic probes because of their sensitivity to hydrogen-containing molecules.
