The HEPS storage ring is one of the largest synchrotron light source accelerators in the world and the largest in China. Its primary function is to store high-energy, high-quality electron beams and generate high-performance synchrotron radiation, according to Pan Weimin, the HEPS project director.As one of the country's key scientific and technological infrastructure projects, HEPS is expected to become one of the brightest fourth-generation synchrotron radiation facilities worldwide and will serve as a research platform for material science, chemical engineering, biomedicine and other fields.

The construction of the HEPS project began on June 29, 2019. The facility is composed of several parts, including accelerators, beamlines, end stations and support facilities.nWE速刷资讯——每天刷点最新资讯,了解这个世界多一点SUSHUAPOS.COM

A synchrotron radiation light source is a source of electromagnetic radiation usually produced by a storage ring. To generate extremely bright light, electrons will be accelerated to near the speed of light in several stages and forced to travel in a closed path.nWE速刷资讯——每天刷点最新资讯,了解这个世界多一点SUSHUAPOS.COM

The commissioning of the storage ring was launched on July 23. A total of 1,776 magnets, over 2,500 power supplies and 578 electron beam position monitors have been installed on the storage ring, with over 100,000 control signals.nWE速刷资讯——每天刷点最新资讯,了解这个世界多一点SUSHUAPOS.COM

"Any small hardware error could affect the trajectory of the electron beam, which is undoubtedly a huge challenge for the commissioning of the storage ring," said Pan.nWE速刷资讯——每天刷点最新资讯,了解这个世界多一点SUSHUAPOS.COM

Commissioning of the HEPS storage ring will continue in the next few months, with the aim of achieving higher beam currents with a sufficiently long beam lifetime for vacuum conditioning and beamline commissioning, said Jiao Yi, deputy head of the HEPS accelerator division.nWE速刷资讯——每天刷点最新资讯,了解这个世界多一点SUSHUAPOS.COM

The HEPS project is expected to be ready for operation by the end of 2025. Once completed, HEPS will be able to emit light that is one trillion times brighter than the sun, and will be open to users in fields such as aerospace, energy, environment, life science and pharmaceuticals, according to IHEP. ■nWE速刷资讯——每天刷点最新资讯,了解这个世界多一点SUSHUAPOS.COM
