Prospects for a neutron EDM measurement with an advanced ultracold neutron source at TRIUMF

Abstract

The TUCAN (TRIUMF Ultra-Cold Advanced Neutron) collaboration is building a new high-intensity ultracold neutron (UCN) source at TRIUMF with the aim of measuring the neutron electric dipole moment (nEDM) with unprecedented precision. TUCAN employs a spallation-driven superthermal UCN production scheme which has been demonstrated with a prototype UCN source. In this article, recent progress on the major components of a new upgraded UCN source and developments in thee context of installation of the nEDM spectrometer are reported.
