江门中微子实验装置正式运行,中国高能物理领域的大科学装置建设实现重大突破
Huan Qiu Wang Zi Xun· 2025-08-26 23:29
来源:环球时报 中微子是组成自然界的最基本的粒子之一,具有极强的穿透力和难以探测的特性,因此又被称为"幽灵 粒子"。确定中微子的质量排序是未来十年粒子物理学领域最受关注的重大问题之一。于泽源表示:"这 一装置的主要科学目标是判断中微子质量顺序,也就是三代中微子的质量轻重问题,在粒子物理和宇宙 学领域都有重要意义。" JUNO探测器不仅能够探测53公里外台山和阳江核电站产生的中微子,还将对来自太阳、超新星、大气 和地球的中微子开展前沿研究,并开启对不活跃中微子及质子衰变等新物理现象的探索。于泽源强 调:"作为高性能中微子探测装置,JUNO不仅帮助我们精确研究反应堆中微子振荡,还可以探测地球中 微子、太阳中微子、超新星中微子,为研究地球、太阳和极端天体提供了新手段,将与我国多个基础研 究领域形成交叉合作,共同进步。"JUNO是由中国科学院高能物理研究所牵头的重要国际合作项目,汇 集了全球17个国家和地区74个科研机构的700余名科研人员。JUNO副发言人、意大利米兰大学及国家 核物理研究所(米兰)教授乔阿基诺·拉努奇表示,江门中微子实验建设取得的重要成就也得益于富有 成效的国际合作。 【环球时报报道 记者 李迅典 ...
