Low-energy neutrons have been a useful probe in fundamental physics studies for more
than 70 years. With advances in accelerator technology, many new sources are spallation …

Controlled modifications of the magnetic response of a two-level system are produced in
dressed systems by one high-frequency, strong, and nonresonant electromagnetic field. This …

High energy physics aims to understand the fundamental laws of particles and their
interactions at both the largest and smallest scales of the universe. This typically means …

Superfluid He 4 is a promising target material for direct detection of light (< 1 GeV) dark

Low counting statistics is one of the most important challenges in modern experiments with
ultracold neutrons (UCN). UCN densities in superthermal sources based on superfluid …

It is thought that equal quantities of matter and antimatter were generated at the moment of
the Big Bang. However, observations of the Universe show that there is a significant excess …

A system for collecting the scintillation light produced by the capture of ultra-cold neutrons
(UCN) on polarized 3 He is discussed and results from simulations of its performance are …

The neutron electric dipole moment experiment at the Spallation Neutron Source (nEDM@
SNS experiment) proposes to measure the nEDM using the spin-dependent capture cross …

In this article we describe the photon detection readout electronics for the nEDM@ SNS
experiment. The chosen" photon counting" architecture, which utilizes high-efficiency silicon …
