Description
The CP-violating neutron electric dipole moment (nEDM) is sensitive to physics beyond the Standard Model which is needed to explain the baryon asymmetry in our universe. The most precise measurement of the nEDM, carried out at Paul Scherrer Institute (PSI), is consistent with zero with an upper limit of $1.8\times10^{−26}~ e$ cm at the 90% confidence level. To reach an order of magnitude better sensitivity, the n2EDM experiment is being commissioned at PSI. In this completely redesigned apparatus, polarized ultracold neutrons from a 5 T superconducting solenoid are transported through six mu-metal layers of the Magnetic Shield Room into a uniform 1 uT precession field via a system a surface current spin transport coils. I will present the design, fabrication, and testing of these coils.
