Initial results of the TRIUMF ultracold advanced neutron source
B. Algohi, D. Anthony, L. Barrón-Palos +83
We report the first results on ultracold neutron production from a new spallation-driven superfluid He (He-II) source at TRIUMF, which is being prepared for a new, precise meas…
Measurement of nuclear spin relaxation time in lanthanum aluminate for development of polarized lanthanum target
K. Ishizaki, H. Hotta, I. Ide +10
The nuclear spin-lattice relaxation time () of lanthanum and aluminum nuclei in a single crystal of lanthanum aluminate doped with neodymium ions is studied to estimate the fe…
Monitoring the build-up of hydrogen polarization for polarized Hydrogen-Deuteride (HD) targets with NMR at 17 Tesla
T. Ohta, M. Fujiwara, T. Hotta +5
We report on the frozen-spin polarized hydrogen--deuteride (HD) targets for photoproduction experiments at SPring-8/LEPS. Pure HD gas with a small amount of ortho-H2 (~0.1%) was li…
Development of a Modular Current-Mode NaI(Tl) Detector Array for Parity Odd (n,γ) Cross Section Measurements
J. T. Mills, J. G. Otero Munoz, K. Dickerson +26
The Neutron Optics Parity and Time-Reversal Violation Experiment (NOPTREX) Collaboration has developed a modular array of 24 NaI(Tl) detectors to measure parity and time-reversal s…
Spin dependence in the -wave resonance of
T. Okudaira, R. Nakabe, S. Endo +24
We measured the spin dependence in a neutron-induced -wave resonance by using a polarized epithermal neutron beam and a polarized nuclear target. Our study focuses on the 0.75~e…
Ultracold Neutron Guide-Coating Facility at U.Winnipeg
T. Hepworth, A. Zahra, B. Algohi +72
We report the construction and commissioning of a new ultracold neutron (UCN) guide-coating facility at the University of Winnipeg. The facility employs pulsed laser deposition (PL…
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…
High sensitivity of a future search for P-odd/T-odd interactions on the 0.75 eV -wave resonance in forward transmission determined using pulsed neutron beam
R. Nakabe, C. J. Auton, S. Endo +27
Neutron transmission experiments can offer a new type of highly sensitive search for time-reversal invariance violating (TRIV) effects in nucleon-nucleon interactions via the same…
