AMS (Alpha Magnetic Spectrometer) is the first space magnetic spectrometer developed for searching antimatter, dark matter and studying cosmic rays in outer space. AMS experiment is an international cooperation project hosted by Ding Zhaozhong, a famous physicist, with the participation of the United States, Russia, China, Switzerland and Italy. Its influence on physics and even the whole natural science and human society is self-evident.
In the past decades, physicists have been expecting to send a magnetic spectrometer into space and put forward various schemes, but it is impossible to manufacture a magnet that meets the above conditions. The Institute of Electrical Engineering of China Academy of Sciences, China Institute of High Energy Physics and China Academy of Launch Vehicle Technology have designed and developed AMS permanent magnet system, and conducted various space environment simulation tests, successfully developing the first large magnet system sent into space.
The experiment of Alpha Magnetic Spectrometer includes three physical objectives that reflect the most important basic theoretical mysteries of today's physics and astrophysics: to find anti-carbon nuclei, anti-helium nuclei and other more important anti-nuclei in the universe to determine whether antimatter exists in the universe; Looking for dark matter that may exist in the universe; Accurately measure the abundance and high energy γ of various isotopes in the universe and explore unknown physical phenomena.
Alpha magnetic spectrometer can measure cosmic rays very accurately and produce many new and meaningful physical information. Alpha magnetic spectrometer can also accurately measure the relative abundance of other isotopes in the universe. These measurements will answer many important questions in cosmology and astrophysics.
