Optimizing neutron moderators for a spallation-driven ultracold-neutron source at TRIUMF
W. Schreyer, C. A. Davis, S. Kawasaki +5
We report on our efforts to optimize the geometry of neutron moderators and converters for the TRIUMF UltraCold Advanced Neutron (TUCAN) source using MCNP simulations. It will use…
First direct constraints on Fierz interference in free neutron decay
K. P. Hickerson, X. Sun, Y. Bagdasarova +40
Precision measurements of free neutron -decay have been used to precisely constrain our understanding of the weak interaction. However the neutron Fierz interference term …
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…
Improved limits on Fierz Interference using asymmetry measurements from the UCNA experiment
Xuan Sun, E. Adamek, B. Allgeier +56
The Ultracold Neutron Asymmetry (UCNA) experiment was designed to measure the -decay asymmetry parameter, , for free neutron decay. In the experiment, polarized ultracold…
The Nab Experiment: A Precision Measurement of Unpolarized Neutron Beta Decay
J. Fry, R. Alarcon, S. Baessler +69
Neutron beta decay is one of the most fundamental processes in nuclear physics and provides sensitive means to uncover the details of the weak interaction. Neutron beta decay can e…
A beamline for fundamental neutron physics at TRIUMF
S. Ahmed, T. Andalib, M. J. Barnes +44
This article describes the new primary proton beamline 1U at TRIUMF. The purpose of this beamline is to produce ultracold neutrons (UCN) for fundamental-physics experiments. It del…
