Oral Presentation

The n2EDM experiment at the Paul Scherrer Institut aims to improve the sensitivity of the measurement of the neutron electric dipole moment (nEDM) by a factor of ten relative to the previous phase of the project. The statistical uncertainty on the extracted nEDM decreases with increasing neutron polarization. Our goal was to conserve the high neutron polarization after the 5 T polarizer magnet...

Oral Presentation

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...

10. Development of polarization transport and Metglas depolarization studies for nEDM@SNS

Xiaozhe Zhu (Graduate Student)

01/09/2026, 12:00

Oral Presentation

The proposed cryogenic neutron electric dipole moment experiment at the Spallation Neutron Source (nEDM@SNS) requires that polarized cold neutrons be transported through a highly nonuniform magnetic field while maintaining high polarization. In this talk, we will present recent progress in magnetic field control and polarization transport studies for the nEDM@SNS experiment, along with...
