UCNatPSI

A new user facility providing ultracold neutrons (UCN) for fundamental physics research, based on accelerator driven spallation neutron production and a superthermal converter, is now routinely operating (live status) at the Paul Scherrer Institut (PSI). Assembly of the PSI UCN source finished in December 2010 with the first production of ultracold neutrons. More on the UCN Source Project ...

UCNatPSI

A new measurement of the neutron electric dipole moment (nEDM), using the Ramsey method of separated oscillatory fields, is in the data taking phase at the PSI UCN source. Already the current upper limit on nEDM (<2.9x10-26 e.cm) constrains some extensions of the Standard Model of particle physics. The new experiment aims at a sensitivity better than 10-27 e.cm to find an eventual nEDM. More on the nEDM Collaboration ...
