Low energy neutron beams are used to address many questions in nuclear physics, particle physics and astrophysics. The scientific issues include elucidating the nature of time reversal noninvariance; understanding the origin of the baryon asymmetry in the Universe; describing the weak interaction between quarks and between nucleons; understanding the origin of the elements in stellar and big bang nucleosynthesis.This book summarizes how spallation neutron sources work and discuss the advantages of pulsed beams in reducing systematic errors in precision measurements. It also describes recent breakthroughs in ultracold neutron production, together with the physics that will be addressed by the new generation of intense neutron sources.

Progress in Particle and Nuclear Physics, Volume 26 covers the significant advances in understanding the fundamentals of particle and nuclear physics. This volume is divided into four chapters, and begins with a brief overview of the various possible ideas beyond the standard model, the problem they address and their experimental tests. The next chapter deals with the basic physics of neutrino mass based on from a gauge theoretic point of view. This chapter considers the various extensions of the standard electroweak theory, along with their implications for neutrino physics. The discussion then shifts to the principles of slow neutrons and their fundamental interactions, as well as some slow neutron experiments. The final chapter surveys the role of strangeness in the context of dense hadronic matter, including strangeness as a probe of the dynamics of relativistic heavy ion collisions and its importance in astrophysics. This book will prove useful to physicists and allied scientists.

Slow-moving, low-energy ultracold neutrons provide an important tool for investigations in physics. They can be kept in hermetically sealed vessels for up to 15 minutes before they decay, allowing researchers sufficient time to observe the action of very weak fields and yielding valuable insights into neutron properties. In addition to describing how these particles are produced, detected, and analyzed, this book provides coverage of improvements in the techniques of ultracold neutron science--with information on how physicists may increase storage times--and explores ways they can be used for fundamental and applied research. Areas of study reported on include the determination of an upper limit to the electric dipole moment of neutrons, improved measurements of decay time, and new approaches to diffraction and diffusion theory. Although the text avoids mathematical detail, this is covered in appendices at chapter ends. The material is intended for specialists in neutron physics.

This chapter reviews the most significant developments that have taken place in the design, construction, and operation of new neutron sources as well as the refurbishment programs of others already serving the neutron-scattering community. Such advances in neutron production devices are to be considered in conjunction with impressive achievements in the optimization of neutron delivery systems as well as in neutron instrumentation which overall resulted in a truly remarkable improvement in neutron count rates. As a result, the capabilities of experimental neutron sources are nowadays larger than ever before, despite there being fewer sources available. It is also worth remarking the coming into line of compact, accelerator-driven neutron sources as well as work carried out at small research reactors which, as exemplified during the past decade, have played an important role in helping the large, user-based facilities to carry out development work geared toward the achievement of full performance.
