Description
Ultracold neutrons (UCN) are neutrons with kinetic energies below approximately 340 neV—low enough to be confined using material or magnetic bottles. These unique properties make UCN an essential tool for precision experiments in fundamental physics, such as probing the Standard Model and searching for new physics beyond it.
At Los Alamos National Laboratory, we operate a UCN source that utilizes a solid deuterium converter driven by a spallation neutron source. This facility has supported a diverse set of experiments—including UCNA, UCNτ, UCNA+, UCNτ+, UCNProBe, and the LANL nEDM project—each contributing to a deeper understanding of neutron properties and symmetries.
In this talk, I will present an overview of the physics program at the LANL UCN source,
highlighting recent achievements, ongoing eUorts, and future directions in the study of
fundamental neutron physics at LANL.
