Abstract: The effort towards a new measurement of the neutron electric dipole moment (nEDM) at the Paul
Scherrer Institute’s (PSI) new high intensity source of ultracold neutrons (UCN) is described. The
experimental technique relies on Ramsey’s method of separated oscillatory fields, using UCN in vacuum
with the apparatus at ambient temperature. In the first phase, R&D towards the upgrade of the RAL/
Sussex/ILL apparatus is being performed at the Institut Laue-Langevin (ILL). In the second phase the
apparatus, moved from ILL to PSI, will allow an improvement in experimental sensitivity by a factor of 5.
In the third phase, a new spectrometer should gain an other order of magnitude in sensitivity. The
improvements will be mainly due to (1)
much higher UCN intensity, (2) improved magnetometry and
magnetic field control, and (3) a double chamber configuration with opposite electric field directions.
