Popis: We discuss a new neutron EDM measurement of 10−28 e cm. For the improved UCN density, we will apply a new spallation UCN source of superfluid He. For magnetometry, 129Xe nuclear spins are injected into a EDM cell, to supress GPE. Performance of the prototype KEK-RCNP UCN source, and the obtained Ramsey resonance spectra are presented.
