IT Home February 5th news, according to the Institute of High Energy Physics, Chinese Academy of Sciences today, from January 19 to 23, 2025, scientific research consisting of the Institute of High Energy Physics, Chinese Academy of Sciences, Ocean University of China and Acoustics, Chinese Academy of Sciences, etc. The team, with the assistance of the “Exploration 3” scientific expedition ship of the Institute of Deep Sea Science and Engineering of the Chinese Academy of Sciences and the “Deep Sea Warrior” manned submersible,Successfully completed the deployment task of the high-energy underwater neutrino telescope (HUNT) detector unit prototype。
The detector equipment deployed this time includes 4 new detector units and 1 LED light source scale unit, etc.They are accurately placed at predetermined points at 1,600 meters deepand successfully connected to the circuit and network system of the national major scientific and technological infrastructure “Sea Scientific Observation Network – Nanhai Undersea Observation Subnet”, has been operating stably, which means that the pre-research work of the HUNT project led by me has taken solid steps. step.
Academician Cao Zhen of the Institute of High Energy led the neutrino research team of the cosmic ray group of the Center for Particle Astrophysics to propose a large scientific installation concept for the next generation of high-energy neutrino telescopes, and originally designed a detector unit with 20-inch MCP-PMT as the core. plan.The device is expected to observe the neutrino celestial point source within two years, and dozens of them are discovered within ten years, leading the development of neutrino astronomy。
The South China Sea is the only optional site area for HUNT installations in my country.The device will cover approximately 600 square kilometers of sea areacan provide a new research platform for marine scientific research. With the LHAASO project team as the core, the research and development of new detector units was completed in two years, and 12 unit prototypes were invested in Lake Baikal in March 2024, and field demonstration was conducted in conjunction with Baikal-GVD experiments.
IT Home Note: Neutrino is an electrically neutral elementary particle, which belongs to fermions and has a spin of 1/2. It interacts with other matter through weak interactions and gravity, where weak interaction forces are short and can usually pass through normal matter almost unhindered and therefore difficult to detect.
Neutrinos can be generated through radioactive decay and nuclear reactions. Since nuclear reactions occur in the sun at all times, and processes such as supernova generation will also be accompanied by violent nuclear reactions.Therefore, the existence of neutrinos can be detected in cosmic rays。
