Abstract
We report the use of deuterated polystyrene (dPS) and deuterated polyethylene (dPE) for the storage of ultracold neutrons (UCN) in an experiment to search for a finite neutron electric dipole moment (nEDM). The Fermi potential of thin film coatings on silicon was measured by cold neutron reflectometry as V(dPS)=(161±10) neV and V(dPE)=(214±10) neV. The UCN loss factor at room temperature of a dPS-coated polystyrene insulator is η=(3±1)×10−4.
