摘要
Borexino 是一款独特的探测器，凭借其极低的放射性本底，能够测量能量在 1 MeV 左右或以下的太阳中微子通量。该探测器建于 Gran Sasso 国家实验室（LNGS）地下实验室，其目标是以前所未有的 5% 精度测量太阳Be 中微子通量。这一目标已成功实现，标志着实验第一阶段的结束。在第一阶段期间，还进行了多项其他重要的太阳中微子通量测量。最近，合作组成功开展了液体闪烁体再纯化活动，旨在降低亚 MeV 能区的主要污染物。借助新的放射纯度水平，Borexino 能够改进现有测量并挑战一系列新测量，包括：改进太阳和地球中微子通量的测量结果；测量 pp 和 CNO 太阳中微子通量；搜寻中微子的非标准相互作用；以及在 SOX 项目背景下，利用人工中微子源研究短基线中微子振荡（搜寻惰性中微子）。
