“…The concept, experimentally pioneered at PNPI [5] and Los Alamos National Lab [6], is based on -neutron production via proton induced spallation on lead [7]; -superthermal UCN production in solid ortho-deuterium (sD 2 ) [1]; -intermediate UCN storage and distribution of UCN on demand to experiments. The main experimental components covering the neutron production and transport are shown in Fig.1.…”

The fundamental properties of the neutron can be studied in detail using ultracold neutrons (UCN) which can be stored and observed for hundreds of seconds. A new user facility providing ultracold neutrons for fundamental physics research has been constructed at the Paul Scherrer Institute, the PSI UCN source. Assembly of the facility finished in December 2010 with the first production of ultracold neutrons. The layout of the source and its operation are briefly discussed.

“…The main experimental components covering the neutron production and transport are shown in Fig.1. PSI's 590 MeV proton beam with up to 2.4 mA beam current is impinging on a heavy water cooled canneloni-type lead spallation target (see (1) in Fig.1) [7]. UCN operation is limited to 1% duty cycle.…”

Ultracold neutrons (UCN) can be stored in suitable bottles and observed for several hundreds of seconds. Therefore UCN can be used to study in detail the fundamental properties of the neutron. A new user facility providing ultracold neutrons for fundamental physics research has been constructed at the Paul Scherrer Institute, the PSI UCN source. Assembly of the facility finished in December 2010 with the first production of ultracold neutrons. Operation approval was received in June 2011. We give an overview of the source and the status at startup.

“…The main components of the source are sketched in Fig.1. Several stages are necessary to first produce neutrons and then slow down these neutrons to the ultracold energy regime: The 590 MeV, 2.2 mA proton beam coming from the PSI cyclotron ( Fig.2a) hits a lead target (Fig.2b) [5], thus creating about 10 neutrons per incident proton. These neutrons are moderated in a heavy water tank at room temperature surrounding the spallation target.…”

Commissioning of the new high-intensity ultracold neutron (UCN) source at the Paul Scherrer Institut (PSI) has started in 2009. The design goal of this new generation high intensity UCN source is to surpass by a factor of ~100 the current ultracold neutron densities available for fundamental physics research, with the greatest thrust coming from the search for a neutron electric dipole moment. The PSI UCN source is based on neutron production via proton induced lead spallation, followed by neutron thermalization in heavy water and neutron cooling in a solid deuterium crystal to cold and ultracold energies. A successful beam test with up to 2 mA proton beam on the spallation target was conducted recently. Most source components are installed, others being finally mounted. The installation is on the track for the first cool-down and UCN production in 2010. 4To whom any correspondence should be addressed. 5 The members of the PSI UCN Project Team are listed at http://ucn.web.psi.ch .
