This article reviews the physics and technology of producing large quantities of highly spin-
polarized He 3 nuclei using spin-exchange (SEOP) and metastability-exchange (MEOP) …

There is a deep connection between cosmology—the science of the infinitely large—and
particle physics—the science of the infinitely small. This connection is particularly manifest in …

A cryogenic apparatus is described that enables a new experiment, nEDM@ SNS, with a
major improvement in sensitivity compared to the existing limit in the search for a neutron …

Novel experimental techniques are required to make the next big leap in neutron electric
dipole moment experimental sensitivity, both in terms of statistics and systematic error …

Following the first experiment on three-body photodisintegration of polarized 3 He utilizing
circularly polarized photons from High-Intensity Gamma Source (HI γ S) at Duke Free …

nEDMSF aims to measure the neutron electric dipole moment ($ d_n $) with unprecedented
precision. In this paper we explore the experiment's sensitivity when operating with an …

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 …

We have observed a linear pressure dependence of longitudinal relaxation time T 1 at 4.2
and 295 K in gaseous He 3 cells made of either bare Pyrex glass or Cs-or Rb-coated Pyrex …

Searches for the neutron electric dipole moment (EDM) are motivated by their highly
suppressed Standard Model value. The observation of a non‐zero signal in the next …

Seeking an upper limit of the Neutron Electric Dipole Moment (nEDM) is a test of charge-
parity (CP) violation beyond the Standard Model. The present experimentally tested nEDM …
