Description
The TRIUMF UltraCold Advanced Neutron (TUCAN) collaboration aims for the measurement of the neutron electric dipole moment (nEDM) with a one order of magnitude improvement of the current best limit. Ultra-cold neutrons (UCNs) suits for such experiment as they can be trapped and stored for several minutes. The collaboration works toward the completion of a new high-intensity UCN source. UCN are produced by a neutron spallation target driven by TRIUMF’s proton cyclotron and a combination of heavy water, liquid deuterium moderator and super-fluid 4He converter. This production scheme has been successfully demonstrated by a prototype UCN source operated from 2017-2019 at TRIUMF. With our newly upgraded source, a statistical nEDM sensitivity of 10−27 e⋅cm would be achieved in 400 days of data taking. The source will also deliver UCNs to a second port that will be open to proposals from users worldwide. This presentation will present an overview of the UCNs source and nEDM experiment installation at TRIUMF.
