The Jiangman underground observatory (JUNO) is a large-scale neutrino detector located in the Jiangmen Underground Neutrino Observatory (JUNO) facility in China. It is designed to study the properties and behavior of neutrinos, which are subatomic particles that have very little mass and interact weakly with other matter.
The main goal of the JUNO project is to measure the properties of neutrinos, such as their mass hierarchy, oscillation parameters, and potential interactions with other particles. It also aims to study the astrophysical sources of neutrinos, such as supernovae and the Sun, and to search for new physics beyond the standard model.
JUNO uses a large spherical detector filled with 20,000 tons of liquid scintillator, a material that emits light when struck by particles. Neutrinos passing through the detector can interact with the scintillator, producing tiny flashes of light that are then detected by photomultiplier tubes. By analyzing the timing and pattern of these flashes, scientists can determine the properties of the neutrinos.
Neutrinos are the most abundant particles in the universe, but they are also the least understood. By studying neutrinos, scientists hope to gain a better understanding of the fundamental laws of physics, the origins of the universe, and the behavior of matter and energy. Neutrinos also have practical applications, such as in medical imaging and nuclear power.
JUNO is expected to make significant contributions to the field of neutrino physics by providing precise measurements of neutrino properties and behaviors. It will also help to answer important questions about the nature of neutrinos and their role in the universe. The data collected by JUNO will be valuable for future research and could potentially lead to new discoveries in particle physics.
