Using neutrino diffraction to study the Earth's core

We explore the possibility of using coherent neutrino scattering to measure the diffraction pattern of crystalline matter in the deep interior of the Earth (or indeed, any planet). We show that natural solar neutrinos are not a suitable radiation source, and by calculating the structure factors for the diffraction of neutrinos from the Earth's core, we constrain the characteristics of a suitable artificial neutrino source. The project is well beyond our present technological capabilities, but might be relatively trivial for a sufficiently advanced civilization, either in Earth's future, or elsewhere in the universe.
