China Universe Lab Detector – Ghost Particles Discovery
Here’s a summary of the provided text about the Jiangmen Underground Neutrino Observatory:
Key Facts:
* What it is: A $300 million neutrino detector located 2,300 feet (700m) underground in China.
* Why underground: The location shields it from cosmic rays and radiation that could interfere with neutrino detection.
* How it effectively works: It contains a large acrylic sphere filled with a liquid that emits light when neutrinos pass through. Neutrinos from nearby nuclear power plants will be studied. The flashes of light are very faint (about 50 per day).
* What it’s trying to find out: The observatory aims to determine the order of neutrino masses (“flavors”) – which is lightest to heaviest. This is a long-standing mystery in particle physics.
* Importance: Understanding neutrino mass hierarchy will help refine models of particle physics, neutrinos, and cosmology.
* construction: Took over nine years to build.
* Structure: The acrylic sphere is contained within a protective cylinder holding 45,000 tonnes of pure water.
In essence,this observatory is a cutting-edge facility designed to unravel one of the fundamental mysteries of the universe – the nature of neutrinos and their masses.
