(Guangzhou Comprehensive News) The construction of the neutron experimental project in Jiangmen, Guangdong has entered the end of the end. It is expected to lead other countries to solve the mystery of neutron quality order and break the United States' leading position in this field.
Comprehensive Xinhua News Agency and Agence France -Presse reported that the core detection equipment of the Jiangmen Zhongmei experiment is located at 700 meters underground, and the detector is placed in a 44 -meter -deep pool in the underground experimental hall.Type of glass balls, stainless steel mesh, cables and coils.
After the installation is completed, the researchers will inject liquid flashing body into the organic glass ball, inject ultra -pure water into the pool where the detector is placed until the entire detector is completely drowned, and then starts to detect the launch of the two surrounding nuclear power plants.Moons.
Narrow microons are one of the basic particles that constitute the world. Because the quality is light and the speed of movement is close to the speed of light, and it rarely reacts with anything, it is very difficult to detect neutron.At present, there are three different quality states of medium microons. Determining which one is the lightest and the heaviest, which can help scientists to solve the unsolved mystery of more physics communities.
Wang Yifang, director of the Institute of High Energy Physics and Chief Scientist of Jiangmen Zhongmei Micro Experiment of the Chinese Academy of Sciences, introduced that the experimental project has attracted 750 scientific researchers from 17 countries and regions and 74 research institutions to participate.
This experimental project costing about 2.2 billion yuan (S $ 410 million) started construction in 2015 and is expected to be officially operated next August.
Wang Yifang told Reuters: "The progress of the US neutron detection station is six years later than us, and the French and Japan's detection stations are two or three years later than us. Therefore, I believe we can get Sino -Micro earlier than everyone earlier than everyone.The result of sub -quality order "
According to Reuters, the U.S. underground deep and neutral experiment projects will be operated around 2030. The project is launched with the support of micro -facilities (LBNF) in the long baseline of the Fermi Laboratory in the United States.
Wang Yifang said that China has supported LBNF. "But from 2018 to 2019, the US Department of Energy requires all national laboratories not to cooperate with China, and the Fermi Lab is forced to suspend cooperation with us."
