Dual mode tomography offers the potential of improved estimation of the composition of a sample from the complimentary of the interaction of the two probes with the sample. We have developed a simultaneous neutron and 90 keV X-ray tomography system that is well-suited to the study of porous media systems such as fuel cells, concrete, unconventional reservoir geologies, limestones and other geological media. We present the characteristic performance of both the neutron and X- ray modalities. We illustrate the use of the simultaneous acquisition through improved phase identification in a concrete core.
