江门地下中微子观测站

The Jiangmen Underground Neutrino Observatory

Marco Grassi

摘要:

江门地下中微子观测站(JUNO)是我国南方正在建设的一个大型高精度液体闪烁探测器。凭借其20 kt的目标质量,它的目标是在1 MeV时实现前所未有的3%能量分辨率。它的主要目标是研究反应堆反中微子的消失,以确定中微子的质量排序,并精确测量混合参数$θ_{12}$,$Δm^2_{12}$和$Δm ^2_{ee}$。它还旨在探测地球内层发生的放射性过程所释放的中微子(地中微子),以及罕见的超新星爆发所产生的中微子。如果闪烁体满足严格的放射性纯度要求,也可以观察到太阳核反应中发射的中微子。这份手稿提供了JUNO物理计划的一些亮点,并描述了探测器的设计,以及正在进行的探测器研发。

英文摘要:

The Jiangmen Underground Neutrino Observatory (JUNO) is a large and high precision liquid scintillator detector under construction in the south of China. With its 20 kt target mass, it aims to achieve an unprecedented 3% energy resolution at 1 MeV. Its main goal is to study the disappearance of reactor antineutrino to determine the neutrino mass ordering, and to precisely measure the mixing parameters $θ_{12}$, $Δm^2_{12}$, and $Δm ^2_{ee}$. It also aims to detect neutrinos emitted from radioactive processes taking place within the inner layers of the Earth (geoneutrinos), as well as neutrinos produced during rare supernova bursts. Neutrinos emitted in solar nuclear reactions could also be observed, if stringent radiopurity requirements on the scintillator are met. This manuscript provides some highlights of JUNO's Physics Programme, and describes the detector design, as well as the ongoing detector R&D.
