dc.description.abstract Ultracold neutrons (UCN) are neutrons with energies below about 330 neV, making it possible to store them in material bottles for hundreds of seconds and guide them into a variety of experiments. Until recently, the available UCN flux has limited the range of problems which can be addressed with UCN. In 2000, a series of experiments at LANSCE demonstrated that a solid deuterium superthermal source, coupled to a spallation target, can potentially provide orders of magnitude improvements in useful UCN density. Since these prototype experiments, a production UCN source has been constructed for the UCNA collaboration in Line B at LANSCE, and another solid deuterium source has been designed to operate at the PULSTAR reactor at NC State university, based on the similar principles. This work will present the initial results and analysis of the LANL UCN source performance and some of the development and design issues for the PULSTAR source. Also a Monte-Carlo analysis of UCN depolarization measurement had been included as a UCN transport study. en_US
