Book Description
This is the final report of a one-year, Laboratory Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL) concerning the investigation of a new method for the experimental exploitation of ultra-cold neutrons. The production and storage of ultra cold neutrons in superfluid helium has been suggested as a tool for the production of high densities of ultra cold neutrons for fundamental nuclear physics as well as for sensitive measurements for condensed matter. A particular application of this technique has been suggested by Doyle and Lamoreaux that involves the trapping of neutrons in a magnetic field within the superfluid helium volume. Neutron decays within the trap volume are detected by the scintillation light produced in the liquid helium. A cryostat and magnetic trap have been constructed as well as a prototype light detection system. This system was installed on a cold neutron beam line at the NIST Cold Neutron Research Facility in the summer of 1997. Preliminary results indicate the detection of helium scintillation light from the detection vessel.

Book Description
Ultra-Cold Neutrons is a complete, self-contained introduction and review of the field of ultra-cold neutron (UCN) physics. Over the last two decades, developments in UCN technology include the storage of UCN in material and magnetic bottles for time periods limited only by the beta decay rate of the free neutron. This capability has opened up the possibility of a wide range of applications in the fields of both fundamental and condensed state physics. The book explores some of these applications, such as the search for the electric dipole moment of the neutron that constitutes the most sensitive test of time reversal invariance yet devised. The book is suitable as an introduction to the field for research students, as a useful compendium of results and techniques for researchers, and is of general interest to nonspecialists in other areas of physics such as neutron, atomic, and fundamental physics and neutron scattering.

Book Description
Ultracold Neutrons is a guide to a fascinating topic. It describes how a simple new idea in experimental neutron physics has changed the landscape of what is often called 'fundamental physics.' Ultracold neutrons (UCNs) are neutrons moving at the low speed of a bicycle rider. They were produced for the first time 50 years ago (in 1968) and are distinguished from ordinary neutrons with much higher energies by their ability to be confined in 'neutron bottles' for durations up to several hundred seconds. This is possible since they are reflected back and forth from the container walls many thousands of times with very little loss. As a result of these long observation times, their properties and interactions with the environment can be studied with superb precision.Directed towards a general readership, this book is an excellent introduction to a field of research that is not highly specialized but touches on many aspects of our physical world, classical as well as quantum mechanical.
