The TRIUMF UltraCold Advanced Neutron source and EDM experiment

ORAL

Abstract

The TUCAN collaboration is installing a new ultracold-neutron source using a superfluid-helium converter driven by a spallation source at TRIUMF’s proton cyclotron. Its world-leading ultracold-neutron-production rate will allow us to search for a neutron electric dipole moment with a sensitivity of 10-27 ecm, an improvement by one order of magnitude over the currently best limit. Such an electric dipole moment would be direct evidence for a new CP-violating mechanism beyond the Standard Model of particle physics and could explain the matter-antimatter asymmetry in the universe.

This presentation will show our latest progress towards completing the source and our preparations for the electric dipole moment experiment.
