Recently, the national major scientific and technological infrastructure - High Energy Synchrotron Radiation Source (HEPS) storage circulating current reached 12 milliamps, which is another important milestone in the construction of HEPS and marks the entry of HEPS accelerators into the fast lane of beam tuning. What is HEPS? It is actually a magnifying glass under construction in Huairou, Beijing. It will emit the brightest synchrotron radiation in the world! It emits light that is 1 trillion times brighter than the sun, making it a powerful tool for exploring the microscopic world and illuminating the path of scientific research. HEPS: Super Eye for Exploring the Microscopic World. HEPS is the first fourth generation synchrotron radiation light source in China and Asia, and one of the world's first light sources with a natural emissivity of 10 picometers. Its core is a new storage ring accelerator with extremely low emissivity, and its physical design is extremely challenging. The synchrotron radiation emitted by HEPS has unique and excellent properties such as high stability, high flux, microbeam diameter, and quasi coherence. Not only can it be used for laboratory research, but it can also solve real problems faced in industrial production. This beam of 'light' can help us quickly see the structure of the virus and provide assistance for scientists to quickly develop vaccines and drugs; Can help us discover how drugs interact with their targets; By observing how lithium ions move in the battery, we can find ways to improve battery capacity and lifespan... After 5 years of construction, on July 23rd at 12:45 this year, the HEPS storage ring was officially turned on for beam adjustment. Since startup, the HEPS accelerator beam tuning team has been continuously tuning 24 hours a day. On August 18th, the storage ring successfully stored 35 beam clusters with a current intensity of 12 milliamps. This indicates that the early equipment installation and debugging were very successful, and also marks a new stage for HEPS light sources. In the coming months, the HEPS beam tuning team will continue to work hard and strive to launch the first beam of light and put it into application within the year. HEPS: A super strong light source that illuminates the forefront of science. HEPS is one of the major national scientific and technological infrastructure projects that China will prioritize during the 13th Five Year Plan period. After completion, HEPS can emit light that is 1 trillion times brighter than the sun, making it one of the fourth generation synchrotron radiation light sources with the highest brightness in the world. It will also be China's first high-energy synchrotron radiation light source, making China one of the world's three largest fourth generation high-energy synchrotron radiation light sources after Europe and the United States. It will complement China's existing light sources and be open to users in the fields of aerospace, energy environment, life medicine, etc. (New Society)
