BEIJING, 25 June (BelTA - China Daily) - The Jiangmen Underground
Neutrino Observatory (JUNO) - now in final preparations before its
commissioning in August - houses the world's most advanced neutrino
detector. At its heart lies a 12-story acrylic sphere containing 20,000
tons of liquid scintillator, shielded by 700 meters of rock and a
44-meter water pool.
This engineering marvel, equipped with 45,000 ultra-sensitive "eyes", which are actually photomultiplier tubes, will achieve an unprecedented 3 percent energy resolution - triple the sensitivity of current detectors.
When neutrinos interact with the scintillator, they emit faint light signals amplified 10 million times. These signals hold keys to fundamental mysteries such as determining which neutrino type is heaviest, simulating stellar explosion mechanisms, and tracing the universe's transformation since the Big Bang.
An international endeavor uniting 700 scientists from 17 countries, including Nobel laureate Arthur McDonald's team, JUNO now forms a neutrino research "trinity" with Japan's Hyper-Kamiokande and America's DUNE, according to the Institute of High Energy Physics, Chinese Academy of Sciences.
