"Search for a Permanent Electric Dipole Moment (EDM) of the Neutron"Dipangkar Dutta , Duke University [Host: Donal Day]
ABSTRACT:
The search for a non-zero neutron EDM is a direct search for time
reversal symmetry violation. Recently, a new experiment has been
proposed to search for the neutron electric dipole moment (nEDM) with
about two orders of magnitude improved sensitivity compared to the
current experimental limit. One of the critical new ideas, which
helps achieve the improved sensitivity, is the use of polarized
Helium-3 as a co-magnetometer. Polarized He-3 is a key new component
of this proposed experiment and thus maintaining its polarization
under the true experimental conditions is essential for the success
of the experiment. Following an overview of the past searches for the
neutron EDM, I will describe the new experiment and the effort
underway at Duke to study the relaxation of polarized He-3 under the
conditions of the new proposed experiment.
