Polarized cold-neutron reflectometry at JRR-3/MINE2 for the development of ultracold-neutron spin analyzers for a neutron EDM experiment at TRIUMF
Takashi Higuchi, Hiroaki Akatsuka, Alexis Brossard +18
The neutron electric dipole moment (EDM) is a sensitive probe for currently undiscovered sources of charge-parity symmetry violation. As part of the TRIUMF Ultracold Advanced Neutr…
A diffuse scattering model of ultracold neutrons on wavy surfaces
S. Imajo, H. Akatsuka, K. Hatanaka +10
Metal tubes plated with nickel-phosphorus are used in many fundamental physics experiments using ultracold neutrons (UCN) because of their ease of fabrication. These tubes are usua…
Estimated performance of the TRIUMF ultracold neutron source and electric dipole moment apparatus
Steve Sidhu, Wolfgang Schreyer, Sean Vanbergen +4
Searches for the permanent electric dipole moment of the neutron (nEDM) provide strong constraints on theories beyond the Standard Model of particle physics. The TUCAN collaboratio…
Characterization of electroless nickel-phosphorus plating for ultracold-neutron storage
H. Akatsuka, T. Andalib, B. Bell +51
Electroless nickel plating is an established industrial process that provides a robust and relatively low-cost coating suitable for transporting and storing ultracold neutrons (UCN…
The Precision nEDM Measurement with UltraCold Neutrons at TRIUMF
Ryohei Matsumiya, Hiroaki Akatsuka, Chris P. Bidinosti +45
The TRIUMF Ultra-Cold Advanced Neutron (TUCAN) collaboration aims at a precision neutron electric dipole moment (nEDM) measurement with an uncertainty of $10^{-27}\,e\cdot\mathrm{c…
Study of Thin Iron Films for Polarization Analysis of Ultracold Neutrons
Hiroaki Akatsuka, Takashi Higuchi, Sean Hansen-Romu +10
The TUCAN (TRIUMF Ultra-Cold Advanced Neutron) collaboration aims to search for the neutron electric dipole moment (nEDM) with unprecedented precision. One of the essential element…
Profiling based Out-of-core Hybrid Method for Large Neural Networks
Yuki Ito, Haruki Imai, Tung Le Duc +4
GPUs are widely used to accelerate deep learning with NNs (NNs). On the other hand, since GPU memory capacity is limited, it is difficult to implement efficient programs that compu…
A fast-switching magnet serving a spallation-driven ultracold neutron source
S. Ahmed, E. Altiere, T. Andalib +47
A fast-switching, high-repetition-rate magnet and power supply have been developed for and operated at TRIUMF, to deliver a proton beam to the new ultracold neutron (UCN) facility.…
First ultracold neutrons produced at TRIUMF
S. Ahmed, E. Altiere, T. Andalib +50
We installed a source for ultracold neutrons at a new, dedicated spallation target at TRIUMF. The source was originally developed in Japan and uses a superfluid-helium converter co…
