In this chapter, neutron experimental techniques are described. The chapter covers the basics of neutron scattering, neutron source characteristics, diffraction techniques, inelastic neutron scattering, instruments for semi-macroscopic structure analysis, detectors, optics, choppers, and some concepts for instrument design. Techniques for both steady and pulsed sources are described, with more emphasis on the latter in view of the recent worldwide trend toward pulsed sources, generally pulsed spallation sources. The source character, even within the class of pulsed sources, has a significant influence on instrument design. Inelasticity effects in the total scattering technique are clearly specified in the chapter. Some details of chopper instruments, including resolution effects, are described, since this class of instruments has recently received considerable innovative development and use over a wide range of science. Recent developments in scintillation detectors are discussed as an alternative technology to more conventional 3He detectors. Optical components are becoming more and more important not only for neutron transport but also for background reduction. Neutron spin-echo techniques are presented as an example of the exploitation of polarized neutrons.
Java Essay: The history and culture of a southern country encompasses many different aspects of the history of Java, Indonesia, offering a unique insight into the Asian country and exploring how its history has impacted on its culture. Author Masatoshi Iguchi explores a panoply of historical events, ranging from the deportation of Japanese Christians in the early 17th century to Batavia – the Indonesian capital now commonly known as Jakarta – to the history of the kingdoms that built Borobudur and Prambanan. The study of stone inscriptions from ancient and medieval times, as well as a number of old records and documents of both domestic and foreign origins, are intertwined with the author’s own insight and thought on the facts and events of Indonesia. Masatoshi’s personal experiences of visiting the indigenous people of Indonesia highlights the interesting nature of a country not yet fully understood. Within the book is an abundance of photographs and drawings, intended to provide readers with visual aids that further their insight into this country’s history and culture. Written in an accessible style, with reference to external sources, Java Essay is a history book that will appeal to readers with an interest in the history and culture of Indonesia. It will prove a fascinating read for academics, as well as travellers and visitors to Indonesia alike.
Hayabusa2 Asteroid Sample Return Mission: Technological Innovation and Advances covers the second Japanese asteroid sample return mission. The purpose of the mission is to survey the asteroid Ryugu's surface features, touch down on the asteroid, form an artificial crater by shooting an impactor, and collect sample materials. This book covers these operations, along with everything known about key technologies, hardware and ground systems upon Hayabusa2's return to Earth in 2020. This book is the definitive reference on the mission and provides space and planetary scientists with information on established technologies to further advance the knowledge and technologies in future space exploration missions. - 2023 PROSE Awards - Winner: Finalist: Chemistry, Physics, Astronomy, and Cosmology: Association of American Publishers - Broadly and comprehensively covers technologies necessary for space exploration missions - Provides a unique focus on small body exploration missions - Covers landing and impact experiments during the proximity operations of Hayabusa2
