HEPS achieved its historical milestone: it passed the performance acceptance organized by the Chinese Academy of Sciences..
The finish of acceptance tests puts HEPS at the top list of the world’s synchrotron X-ray research facilities, marking one generation leap for China’s synchrotron radiation capabilities. Its electron beam emittance achieved 57pm·rad under 100 milliamps beam current. A suite of world-class performance beamlines has been commissioned, such as state-of-the-art the hard x-ray imaging beamline and the structural dynamics beamline. |

The China-Brazil Joint Laboratory of Synchrotron Radiation Science and Technology (CBJSync) was established..
The Brazilian Center for Research in Energy and Materials (CNPEM), a non-profit organization supervised by Brazil’s Ministry of Science, Technology and Innovation (MCTI), and the Institute of High Energy Physics (IHEP) of the Chinese Academy of Sciences (CAS) inaugurated the China-Brazil Joint Laboratory for Synchrotron Science and Technology (CBJSync) on June 25, 2025. The initiative marks the beginning of in-person scientific exchange, with Chinese researchers working at the CNPEM campus in Campinas, São Paulo, and Brazilian researchers hosted at the IHEP campus in Beijing. Sponsored by China’s Ministry of Science and Technology (MOST), MCTI and CAS, the CBJSync represents a significant milestone in the partnership between CNPEM and IHEP—a collaboration formalized in 2023 and supported by both CAS and MCTI. |

HRH Princess Maha Chakri Sirindhorn of Thailand Visited HEPS..
The Princess first visited IHEP in 2011, when she toured the Beijing Electron Positron Collider, China’s first large science facility. In 2017, she witnessed the signing of cooperation agreements between IHEP and three Thai universities, significantly advancing cooperation in both neutrino and collider experiments. In 2023, IHEP had the honor of receiving the Princess at the Jiangmen Underground Neutrino Observatory (JUNO) in Guangdong. CAO expressed his hope that the Princess’s fourth visit—to HEPS—would further expand bilateral cooperation in synchrotron radiation light sources and promote friendship between China and Thailand. |
