The new ultracold neutrons source at PSI

Creators

Description

At PSI we are building a new, high-intensity source of ultracold neutrons (UCN) which will deliver UCN densities in excess of 1000 UCN/cm3. Its essential elements are a pulsed 590 MeV proton beam with 2 mA intensity and 1% duty cycle, a lead spallation target, a large heavy water moderator and 30 l of solid deuterium at 5 K as a converter. The source is in its commissioning phase and is expected to deliver first UCN by April 2010 after the accelerator shutdown. As a first experiment we will perform a new measurement of the neutron electric dipole moment (n-EDM). The characteristics of the source, the corresponding R and D programm and the commissioning program are reported.
