The UCN Source at LANSCE

ORAL

Abstract

A new source of ultra-cold neutrons (UCN), using on a solid deuterium moderator has been built at the Los Alamos Neutron Science Center (LANSCE). Closely based on a prototype that was tested at Los Alamos, the new source supplies two UCN beam lines: one for the UCNA experiment and the other for development of the Los Alamos UCN EDM experiment and a neutron lifetime experiment. The LANSCE 800 MeV proton beam creates spallation neutrons from a tungsten target. The spallation neutrons are cooled with a cold polyethylene moderator. These cool neutrons then interact with solid deuterium and become UCN. This talk will present a summary of the current source design, it UCN production capabilities, and some aspects of UCN delivery to planned experiments
