The TRIUMF UltraCold Advanced Neutron source

ORAL

Abstract

The TUCAN collaboration is building a unique ultracold-neutron source using superfluid helium and liquid deuterium to moderate neutrons from a spallation source. Scheduled to go into operation in 2022 we expect it to be the world’s strongest source for ultracold neutrons, which will allow us to search for an electric dipole moment of the neutron with a sensitivity of 10-27 e·cm.

This presentation will show results we collected with a prototype source and how we use this data to estimate and optimize the performance of the new source. It will also cover the engineering challenges and current installation progress.
