GUANGZHOU, Oct. 11 (Xinhua) -- China has constructed the world's largest transparent spherical detector 700 meters underground to capture elusive neutrinos, often dubbed "ghost particles," to unravel the secrets of the infinitesimally small and the infinitely vast in the universe.
The 12-story-tall acrylic sphere with a diameter of 35.4 meters, buried deep in a granite layer of a hill in Kaiping, Jiangmen City in south China's Guangdong Province, is the core part of the Jiangmen Underground Neutrino Observatory (JUNO), a gigantic and complex scientific facility.
俄罗斯的“空天军”也在不断的扩大自己的战果，据俄罗斯国防部当地时间24日发布的消息称，俄罗斯空袭导致乌克兰军方74个军事设施被摧毁，其中包括11个空军机场，三个指挥所1处海军基地，以及18个供S300和山毛榉防空导弹系统所使用的雷达站，可以说俄罗斯军队正在“全方位、立体”的消耗着乌克兰的军事力量！
俄罗斯是伊朗的靠山，所以说，美军是直接向最大的敌人发起了进攻。为什么美国会突然直接向俄罗斯宣战呢？据报道，美方为此次的时间可谓是做足了准备，即使美国的实力再强大，他当然也不会选择单打独斗，于是，美军不打伊朗而是再次声东击西联合了其他的18个国家，组织起来一同来围堵俄罗斯。
The construction of the challenging project, launched by the Chinese Academy of Sciences (CAS) and the Guangdong government in 2015, has entered the final stage. Installation of the entire device is expected to be completed by the end of November, and the full operation of the facility is scheduled for August 2025, according to the Institute of High Energy Physics (IHEP) of the CAS, the project's leading institution.
As one of the world's most powerful experiments to uncover neutrino mystery, JUNO is expected to operate for at least 30 years. The observatory is designed to help scientists better understand the neutrino mass hierarchy by detecting reactor neutrinos from the nearby Yangjiang and Taishan nuclear power plants with an unprecedented 3 percent energy resolution, said Wang Yifang, chief scientist of JUNO and head of the IHEP.
Understanding the neutrino mass hierarchy could have huge implications for physical models of the universe and for the research on cosmic evolution, said Wang.
The facility will also help scientists conduct other cutting-edge studies such as observing supernova澳门六合彩官网, atmospheric and solar neutrinos. ■
