Description

The n2EDM experiment of an international collaboration at the Paul Scherrer Institute (PSI) aims to improve the sensitivity of the measurement of the neutron electric dipole moment by a factor of ten with respect to its predecessor. A most efficient neutron spin transport is vital to achieve such a sensitivity. We present an overview of the spin transport coil system, the three main channels of neutron depolarization in the apparatus, and preliminary results on the performance.
