Oral Presentation

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.
Our TRIUMF...

Oral Presentation

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...

7. Measurement of the cold-neutron flux for the TUCAN source

Ryuto Fujitani (Kyoto University)

Oral Presentation

The TRIUMF UltraCold Advanced Neutron (TUCAN) project has constructed a high-intensity ultracold-neutron source at TRIUMF for a neutron electric dipole moment experiment. The UCN production utilizes the superthermal method in which inelastic scattering in superfluid helium converts cold neutrons into ultracold neutrons. One of the factors critical for the performance of the UCN source is the...
