He-3 Spin transport system at the nEDM@SNS experiment

The electric dipole moment (EDM) violates a fundamental symmetry of nature called charge parity (CP) conjugation, which is akin to reversing the arrow of time. Discovery of a nonzero EDM of an elementary particle would help to explain the predominance of matter over antimatter in the universe, even though both were generated in equal quantities during the Big Bang. The goal of the nEDM@SNS experiment at Oak Ridge National Laboratory is to improve the sensitivity to the neutron EDM by two orders of magnitude. This experiment will measure the precession frequency of free neutrons, using the polarized He-3 isotope as a co-magnetometer. In this talk, I will discuss the design of a system of magnetics used to transport polarized He-3 into the EDM measurement cell.
