地球中微子的探测:我们能让Gnus为我们工作吗?
Detection of Geoneutrinos: Can We Make the Gnus Work for Us?
摘要:
半个世纪以来,从地球的天然放射性中探测电子反中微子一直是中微子研究者的目标。它是由KamLAND协作组织于2005年完成的,为研究地球的放射性含量开辟了道路,对地质学具有非常重要的影响。新的探测器正在运行(KamLAND和Borexino),正在建造(SNO+)和正在提出(Hanohano,LENA,Earth和其他),这些探测器将超越最初的观测,并以其他方式进行有趣的地球物理和地球化学研究。在这里,我们描述了正在采取的方法(大型液体闪烁仪器),实验和技术的挑战(光学探测器,方向性),以及这一领域的发展前景。在粒子物理学(中微子振荡和层次确定)、天体物理学(太阳中微子、超新星、奇异星)以及核反应堆远程监测的实际问题中,都有相关的副产品。
英文摘要:
The detection of electron anti-neutrinos from natural radioactivity in the earth has been a goal of neutrino researchers for about half a century. It was accomplished by the KamLAND Collaboration in 2005, and opens the way towards studies of the Earth's radioactive content, with very important implications for geology. New detectors are operating (KamLAND and Borexino), building (SNO+) and being proposed (Hanohano, LENA, Earth and others) that will go beyond the initial observation and allow interesting geophysical and geochemical research, in a means not otherwise possible. Herein we describe the approaches being taken (large liquid scintillation instruments), the experimental and technical challenges (optical detectors, directionality), and prospects for growth of this field. There is related spinoff in particle physics (neutrino oscillations and hierarchy determination), astrophysics (solar neutrinos, supernovae, exotica), and in the practical matter of remote monitoring of nuclear reactors.
