Neutrino Physics
Studying the masses and properties of these nearly-massless, weakly-interacting particles
Principal Investigator: Rex Tayloe
Weak Interactions with Neutrons
We measure parity violation through high-precision measurements of radiative neutron capture and neutron spin rotation.
Principal Investigator: Michael Snow
Measuring the neutron lifetime using Ultracold Neutrons
The physics of UCN production in solid oxygen involving magnon (spin wave) exchanges is fundamentally different from the well-known phonon mechanism in solid deuterium
Principal Investigator: Chen-Yu Liu
Electric Dipole Moment (EDM) Searches
This class of experiments searches using a variety of techniques for the spontaneous separation of positive and negative charges along the spin direction of a sub-atomic particle. A discovery of an EDM could lead to an explanation of the surplus of matter left over following the Big Bang. All such searches look for the effects of a strong, external electric field on the system.
Search for a Neutron EDM
Trapping ultra-cold neutrons in a liquid helium bath to measure their precession. A collaboration (nEDM) was formed to construct an experiment at the SNS to look for a finite electric dipole moment of the neutron.
Principal Investigators: Josh Long, Chen-Yu Liu, Mike Snow and Hans-Otto Meyer
Search for an Electron EDM
Measuring the induced magnetic field of electron in a garnet crystal
Principal Investigator: Chen-Yu Liu
Search for a Nuclear EDM with Storage Rings
Looking for spin direction shifts as particles revolve around a beam storage ring
Principal Investigator: Edward Stephenson
