Reference News Network, November 24 report. According to Kyodo News, on November 20, the Jiangmen Underground Neutrino Observatory (JUNO) held an event to celebrate the completion of its construction. JUNO is a facility in China for observing fundamental particles called neutrinos, and it was open to the media before the event. The head of JUNO pointed out that China will strive to promote research at world-class level and catch up in the field of neutrino research.
According to reports, JUNO is one of the next-generation basic particle observation facilities, along with the "Hyper-Kamiokande" detector being built in Gifu Prefecture, Toyama City, Japan. It officially started operation in late August. There are three types of neutrinos in nature, which have extremely small differences in mass, and one of the main purposes of JUNO is to measure the mass of these neutrinos.
To reach the observation area located 700 meters underground, one needs to take a track vehicle. Journalists were allowed to visit the room above the latest neutrino detection device and the cooling equipment. JUNO revealed on that day that it had successfully narrowed down the range of observational values required to measure the mass of neutrinos.
It is rare for a facility to announce results within less than three months of full operation. Cao Jun, Director of the Institute of High Energy Physics, Chinese Academy of Sciences, explained in an interview that the device has strong detection capabilities and can efficiently collect data.
The Communist Party of China held an important meeting in October, proposing to increase the proportion of investment in basic research. Particle physics is considered one of the key areas. (Translated by Ma Xiaoyun)
