Paul Scherrer Institut（PSI）的新型高强度超冷中子（UCN）源已于2009年开始调试。这一新一代高强度UCN源的设计目标是将目前可用于基础物理研究的超冷中子密度提高100倍，最大的推力来自于对中子电偶极矩的研究。PSI UCN源是基于通过质子诱导铅溅射产生中子，然后在重水中进行中子热化，并在固体氘晶体中进行中子冷却以获得冷和超冷能量。最近成功地进行了高达2mA的质子束在溅射靶上的束流测试。大多数源组件已安装，其他组件最终安装。该装置正在轨道上的第一次冷却和UCN生产在2010年。
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.
