Description
Ultracold neutrons (UCNs) are a powerful tool for probing fundamental physics, enabling precision measurements in a variety of research areas, such as beta decay, electric dipole moments, and gravitational quantum states. To advance these experimental efforts it is necessary to develop new, high-density UCN sources capable of providing order-of-magnitude improvements in statistical sensitivity. The TRIUMF UltraCold Advanced Neutron (TUCAN) collaboration is building a new spallation-driven superthermal UCN source using superfluid helium, which will enable a new generation of UCN-based precision experiments. The performance of this source will depend on the storage lifetime of UCNs in the superfluid volume, which is expected to have a temperature-dependence given by $\tau^{-1} = BT^7$. In this talk, I will present the results of experimental efforts to measure this dependence using a prototype UCN source.
