Intended Audience: 
The motivation for the Ultra Cold Neutron (UCN) collaboration is to measure the electric dipole moment (EDM) of the neutron. Previous measurements yield an upper limit of 2.9 x10-26 e cm, performed at ILL in 2006. UCN will further constrain the limit by minimizing the uncertainties from systematic effects. To reduce these effects, two atomic sources are introduced in the system, 199Hg and 129Xe. We are developing a UV laser to perform NMR measurements on the atomic sources to measure the magnetic field applied to the neutrons. This is the first time two atomic sources will be used together, called a dual co-magnetometer.
