Description

The Japanese-Canadian TUCAN (TRIUMF UltraCold Advanced Neutron) collaboration is currently building a next generation ultracold neutron source at TRIUMF, Vancouver, Canada. This superthermal source is based on conversion of fast neutrons from a spallation target to the ultracold regime in liquid, superfluid helium. We expect to deliver around ${10}^7$ UCN per second at the exit of the source. The presentation will provide an overview of the source concept, its moderator and ultracold neutron design and the cryogenic infrastructure required for its operation. Experiments planned will also be briefly introduced.
