Ultracold neutrons (UCN) can help solve some of the universe's fundamental puzzles: very high precision experiments are possible due to observation times lasting up to hundreds of seconds.

However, experiments, such as searches for the neutron electric dipole moment, measurements of the neutron lifetime, and tests of neutron-gravity-interaction tests have been statistics limited.

The TUCAN collaboration aims to search for the neutron electric dipole moment (nEDM) with an unprecedented precision of $10^{-27}$cm. To achieve this sensitivity, the development of the world's highest-intensity ultra-cold neutron (UCN) source is essential. A critical component of this source is the advanced cryogenic system, designed to maintain superfluid helium at optimal temperatures under...

The TRIUMF Ultracold Advanced Neutron (TUCAN) source produced UCNs for the first time in 2025. As part of the characterization of this new UCN source, we installed a prototype storage cell for the TUCAN EDM experiment with a guide geometry similar to that expected in a real experiment. We measured the filling, storage, and emptying of UCNs with this cell, optimizing the timing sequence to...
