Comparison of Thermal Neutron and Hard X-ray Dark-Field Tomography. 
High visibility (0.56) neutron-based multi-modal imaging with a Talbot-Lau interferometer at a wavelength of 1.6 Å is reported. A tomography scan of a strongly absorbing quartz geode sample was performed with both the neutron and an X-ray grating interferometer (70 kVp) for a quantitative comparison. Small scattering structures embedded in the absorbing silica matrix were well resolved in neutron dark-field CT slices with a spatial resolution of about 300 μm. Beneficial effects, such as monochro...    »
