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.…
Wigner-Eckart Theorem and the False EDM of Hg
Wolfgang Klassen, Jeffery W. Martin, Guillaume Pignol
In neutron electric dipole moment experiments, 199Hg is used as a comagnetometer. The comagnetometer suffers from a false EDM arising in leading order from a gradient dBz/dz in the…
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…
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…
