Join hands to step up to a new level and forge ahead with Chinese path to modernization to open a new chapter in the coordinated development of Beijing Tianjin Hebei (reporter Wang Bin) At the Yanqi Lake in Huairou, a device that looks like a "magnifying glass" is particularly eye-catching. It covers an area of about 976 mu and is about the size of 90 football fields. In March of this year, the first electron beam of the device was successfully accelerated here, taking another step towards producing the world's "brightest synchrotron light". The reporter of Beijing Youth Daily learned that the "magnifying glass" shaped building cluster is carrying the core device of Huairou large device cluster - high-energy Synchrotron light source, which will be the first high-energy Synchrotron light source in China, and will also become one of the fourth generation Synchrotron light source with the highest brightness in the world. It is expected that the device construction will be completed by the end of 2025. According to the relevant person in charge of the Beijing Municipal Development and Reform Commission, as an important carrier for building and cultivating national strategic scientific and technological strength and the core support for Beijing's construction of an international scientific and technological innovation center, the Beijing Huairou Comprehensive National Science Center continues to focus on original innovation and basic research, and focuses on tackling key core technical problems that are "stuck", achieving more breakthroughs from 0 to 1. In recent years, a series of "great power weapons" have been completed here. Among them, the "magnifying glass", known as the "tool for detecting the micro world," is particularly eye-catching. Li Jingyi, deputy director of the accelerator department of the high-energy Synchrotron light source of the Institute of High Energy Physics of the Chinese Academy of Sciences, introduced that in the late 1940s, the scientific community found that, like an umbrella rotating rapidly in the rain, clusters of water droplets would fly along the tangent direction of the umbrella edge. When the high-energy electron beam was gyrating on the annular Synchrotron at a speed close to the speed of light, it would also emit electromagnetic waves in the tangent direction, which is Synchrotron radiation light. Compared with conventional light sources, Synchrotron radiation has high brightness and wide coverage spectrum. It is like a super X-ray machine, with which people can observe the microstructure of matter. Since then, countries around the world have begun to build special Synchrotron light source to promote the development of science and technology. In June 2019, the high energy Synchrotron light source project broke ground. The project is undertaken by the Institute of High Energy Physics of the Chinese Academy of Sciences, mainly including accelerators, beam line stations and auxiliary facilities, with a construction period of 6.5 years. After nearly 4 years of construction, three main buildings have grown on the once barren grassland. In March this year, the high-energy Synchrotron light source linear accelerator "full energy" beam, the first to usher in a "good start", every second there are 10 billion electrons "shooting" from the electron gun, of which about 90% of the electrons can successfully reach the end. This also means that this "great power weapon" has entered the parallel stage of scientific research equipment installation and beam adjustment, taking a further step towards producing the world's brightest synchronous light. At present, the installation and equipment joint commissioning of the electron secondary accelerator intensifier of the high-energy Synchrotron light source have been basically completed, and the largest "annular acceleration runway" - the storage ring accelerator with a beam orbit circumference of about 1360.4 meters, and the beam line station carrying out synchronous optical processing and user experiments are also stepping up their installation. After this large device is put into operation, the electron beam in the storage ring will generate high brightness, resolution, and energy synchronous light during the "running" process, helping researchers "illuminate" experimental samples and better understand
