A Manufacturing Technique for Binary Clathrate Hydrates for Cold and Very Cold Neutron Production
Intense sources of very cold neutrons (VCNs) would be beneficial for various neutron scattering techniques and low-energy particle physics experiments. Binary clathrate hydrates hosting deuterated tetrahydrofuran (THF-d) and dioxygen show promise as potential moderators for such sources due to a rich spectrum of localized low-energy excitations of the encaged guest molecules. In this article, we present a reliable manufacturing technique for such hydrates. Neutron diffraction data confirm their clathrate structure as type II (CS-II), determine their purity, and cage occupancy. Furthermore, we present data on the thermal expansivity of THF-d- and THF-d-O<sub>2</sub>clathrates, drawing attention to them as an interesting case study for the complex structure and dynamics of this class of material.
