New precise measurements of the neutron electric dipole moment (nEDM) are strongly motivated by the tight constraints they will place on new sources of CP violation. A number of experiments are commencing in the next few years that aim to reduce the experimental uncertainty on the nEDM by more than an order of magnitude. The experiments pursue a variety of complementary techniques. The TUCAN (TRIUMF Ultra-Cold Advanced Neutron) EDM experiment is one such experiment which combines a spallation-driven superthermal He-II source of ultracold neutrons with a room-temperature nEDM spectrometer.
