Our celebration of Dr. Douglas Wong's successful doctoral dissertation defense, with his supervisor, Dr. Chen-Yu Liu.

Dissertation Title: The Nuts and Bolts of the Neutron Electric Dipole Moment (nEDM) Experiment at Los Alamos National Laboratory

Abstract: The neutron electric dipole moment (nEDM) experiment that is currently being developed at Los Alamos National Laboratory (LANL) will use ultracold neutrons (UCN) and Ramsey’s method of separated oscillatory fields to search for a nEDM with a statistical uncertainty of 2 x 10^{-27} e cm in 5 calendar years of running. We present the following: (1) a description of the LANL nEDM experiment, control systems, and data acquisition system, (2) measurements and analysis of data taken during the commissioning of experimental components and the UCN beamline, (3) an analytical model that provides a simple parameterization of the input UCN energy spectrum on the beamline, and (4) Monte Carlo simulations of UCN transport from the LANL UCN source into the experimental apparatus.
