According to the Russian Science Information magazine, a large-scale international physical experiment project named "OPERA" was launched by the countries concerned. The main goal of this project is to form a directional neutrino beam at CERN in Geneva with the help of proton accelerator, and then the neutrino beam flies 730 kilometers underground at the speed of light, reaching the underground laboratory in Italy's Grand Sasso Mountain, where it passes through the detector, leaving traces and leaving quickly. According to the report, as participants in the "OPERA" project, Russian and Ukrainian experts are cooperating to develop a detection system aimed at recording the activities of this mysterious particle. Ukraine has also undertaken the task of producing scintillation materials for this research. Grigne Fu, director of the Institute of Scintillation Materials of the Ukrainian Academy of Sciences, said that in order to capture neutrinos, it is necessary to build a huge and complex detection room. The wall of the detection room is composed of special bricks composed of multiple layers of latex and lead, and plastic scintillation materials are filled between the bricks. This material can react to the low-light-level explosion caused by various invisible radiation such as neutrino beams. Automatic instruments can record the light explosion and determine which brick the light explosion occurred on. The researchers took the brick out of the wall, developed the latex layer inside and measured the parameters of the reaction traces left on it to determine whether these traces were left by neutrinos. He said that each brick has 57 layers of latex, and it takes dozens of hours to detect a brick with the most advanced computers and special equipment. At present, Ukrainian experts are improving the production process of scintillation materials. According to the "OPERA" project order, Ukraine will produce 33,000 scintillation materials with a length of 7 meters and a total weight of about 70 tons. Neutrino is one of the basic particles that make up matter, and it exists widely in the universe. It is so small that it can easily penetrate the earth. This kind of particle basically does not interact with any substance, so it is difficult to be captured and detected, and it is called "invisible man" in the universe. Experts believe that the "OPERA" project will help the scientific community to understand the characteristics of neutrinos. This kind of particle is directly related to the development of the universe and the existence of "dark matter", which may become the key to open the door to new physics for mankind.
