UCNatPSI


A new user facility providing ultracold neutrons for fundamental physics research, based on accelerator driven spallation neutron production and a superthermal converter, has been constructed at the Paul Scherrer Institut (PSI), the PSI UCN source. Assembly of the facility 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 being designed 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 two orders of magnitude improvement in sensitivity to find an eventual nEDM. This will be achieved by better control of systematic effects and the higher UCN flux provided by the new PSI source. More on the nEDM Collaboration ...
