A New High-Intensity Source for Ultracold Neutrons
K. Abe, S. Ahmed, B. Algohi +78
The TRIUMF UltraCold Advanced Neutron (TUCAN) collaboration has completed a new superthermal source for ultracold neutrons (UCNs) at TRIUMF. It uses neutrons from a spallation targ…
A magnetic environment with reproducible spatio-temporal magnetic conditions at picotesla level
Philipp Wunderl, Maximilian Huber, Florian Büttiker +16
Walk-in, picotesla-scale environments are essential for measurements of biomagnetism and fundamental physics. However, conventional rooms require typical active dynamic compensatio…
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…
Initial Performance of the TUCAN Magnetically Shielded Room
S. Ahmed, B. Algohi, D. Anthony +64
The TRIUMF Ultracold Advanced Neutron (TUCAN) collaboration has commissioned a large magnetically shielded room to be used for measuring the neutron electric dipole moment (nEDM) t…
Scalar-Magnetometer Search for Ultralight Dark Photon Dark Matter with a Single-Site, Two-Sensor Array: A 6-Channel DTFT Likelihood Analysis with Scalar Optically Pumped Magnetometers
Peisen Zhao, Ole Behrens, Maja Benning +6
We report on a laboratory search for ultralight dark photon dark matter using a single-site, two-sensor scalar magnetometer array. The experiment employs two scalar optically pumpe…
