论文摘要
SNO+实验是一个大规模的多用途中微子实验，位于加拿大Snolab的地下2公里。 SNO+检测器的萨德伯里中微子天文台的继任者继承了许多原始基础设施，包括直径为12米的丙烯酸血管，该容器充当主要检测器体。 SNO+实验最初充满了超纯水，已完成操作作为水切伦科夫探测器，对多个不可见的核子衰变模式设定了新的限制，对$^8 \ mathrm {b} $ solar nutrinos进行了测量，并使反应堆在纯水中进行了反激抗炎的反应器反炎。现在已将检测器介质替换为液体闪烁体，并且正在追求一个新的物理程序，包括对太阳中微子的测量和$Δ\ mathrm {m}^2_ 2_ {12} $从反应堆抗毒液中。液体闪烁体将以> 4吨的$^{\ Mathrm {nat}}} \ Mathrm {TE} $掺杂，以启用搜索NeutMinoless Double Beta衰减。
The SNO+ experiment is a large-scale, multipurpose neutrino experiment situated 2 km underground at SNOLAB in Canada. Successor to the Sudbury Neutrino Observatory, the SNO+ detector has inherited much of the original infrastructure including the 12-m diameter acrylic vessel which serves as the main detector body. Initially filled with ultrapure water, the SNO+ experiment has completed operations as a water Cherenkov detector, having set new limits on multiple invisible nucleon decay modes, performed measurements on $^8\mathrm{B}$ solar neutrinos, and made the first observation of reactor antineutrinos in pure water. The detector medium has now been replaced with liquid scintillator, and a new physics programme is being pursued including measurements of solar neutrinos and $Δ\mathrm{m}^2_{12}$ from reactor antineutrinos. The liquid scintillator will be doped with >4 tonnes of $^{\mathrm{nat}}\mathrm{Te}$ to enable a search for neutrinoless double beta decay.
