Characterization of the new Ultracold Neutron beamline at the LANL UCN facility

The neutron electric dipole moment (nEDM) experiment that is currently being developed at Los Alamos National Laboratory (LANL) will use ultracold neutrons (UCN) and Ramsey's method of separated oscillatory fields to search for a nEDM. In this paper, we present measurements UCN storage transport performed during the commissioning new beamline LANL source demonstrate sufficient number stored polarized achieve statistical uncertainty $\delta d_n = 2\times 10^{-27}$~$e\cdot\text{cm}$ in 5 calendar years running. We also an analytical model describing data provides simple parameterization input energy spectrum on beamline.
