PanEDM storage times and emptying efficiency
The PanEDM experiment seeks to measure the neutron's permanent electric dipole moment (EDM) to an unprecedented sensitivity. The new SuperSUN source at the ILL will supply the PanEDM experiment with ultra-cold neutrons (UCNs). This proposal aims to perform a functional test of the PanEDM components for use with polarized UCNs at the PF2/EDM beamline. Such an experiment measures the neutron storage lifetime $T_0$, the UCN polarization lifetime $T_1$, emptying efficiency of the storage volume, and the polarization visibility $\alpha$, factors which in part determine the ultimate statistical reach of PanEDM. In addition, it characterizes the intended coatings for storage cells, and tests the switches and valves constructed for filling and emptying polarized UCNs. These data are also of interest to SuperSUN, the HOPE neutron lifetime experiment, and any future experiments using UCNs from liquid-helium-based sources.
