Abstract

The Neutron Electric Dipole Moment (NEDM) experiment is an upcoming experiment at ORNL to measure the size of an electric dipole moment inside of the neutron. This is being done to probe CP asymmetries that could give rise to a matter dominated universe. The experiment will utilize a nuclear reaction that outputs scintillation light in a manner that depends on the alignment of the spins of the reactant particles. This light will be detected and used to measure the NEDM. The amount of light collected for measurement will impact the accuracy of the results; the more photons collected the better the accuracy. However, during the process of transporting light from the reaction site to the light detectors, much of the scintillation light will be lost. Herein are the results of tests conducted on various parts of the NEDM apparatus in order to characterize and optimize light collection for the coming experiment.
