Description
To achieve the target neutron electric dipole moment sensitivity of $d_n \sim 10^{-27}$ e.cm for the TUCAN EDM experiment, efficient polarization transport of ultracold neutrons is required. Therefore, magnetic spin transport guiding coils are designed to adiabatically transport and manipulate polarized neutrons from the superconducting neutron polarizer to the precession chamber and back out to the neutron analyzer without significant depolarization. The design utilizes magnetic scalar potential modeling to create a specific field taper. In this presentation, I will describe the determination of the required magnetic field profile, the modelling approach, and the manufacturing of prototype guiding coils designed to taper the magnetic field from the outer shield region down to approximately 1 µT inside the precession chamber.
