反中微子探测器在核安全中的应用:当前能力和未来前景
Nuclear Security Applications of Antineutrino Detectors: Current Capabilities and Future Prospects
摘要:
反中微子是电中性的,几乎没有质量的基本粒子,在核反应堆的核心和核爆炸中大量产生。自发现以来的半个世纪里,对它们性质的理解和探测器技术的重大进展为一门新学科打开了大门:应用反中微子物理学。由于反中微子与核裂变过程有着千丝万缕的联系,许多感兴趣的应用都是在核不扩散方面。本白皮书介绍了与防扩散相关的应用反中微子物理学的全面调查,总结了该领域的最新进展,描述了这一新兴学科与其他正在进行的基础和应用反中微子研究的重叠,并绘制了未来应用的研究和开发路线。它旨在为政策制定者,研究人员和更广泛的核不扩散社区提供资源。
英文摘要:
Antineutrinos are electrically neutral, nearly massless fundamental particles produced in large numbers in the cores of nuclear reactors and in nuclear explosions. In the half century since their discovery, major advances in the understanding of their properties, and in detector technology, have opened the door to a new discipline: Applied Antineutrino Physics. Because antineutrinos are inextricably linked to the process of nuclear fission, many applications of interest are in nuclear nonproliferation. This white paper presents a comprehensive survey of applied antineutrino physics relevant for nonproliferation, summarizes recent advances in the field, describes the overlap of this nascent discipline with other ongoing fundamental and applied antineutrino research, and charts a course for research and development for future applications. It is intended as a resource for policymakers, researchers, and the wider nuclear nonproliferation community.
