The Institute of High Energy Physics (IHEP) of the Chinese Academy of Sciences and the Spanish Consortium for the Construction, Equipping and Exploitation of the Synchrotron Light Source (CELLS) signed a cooperation agreement on July 26, 2025 in Beijing. This collaboration aims to advance the development of synchrotron science and technology by leveraging the expertise and facilities of both parties, defining the specific collaborative activities and programs between IHEP and CELLS. It will focus on three main areas: accelerator technology, experimental beamline technology, and scientific cooperation.

The High Energy Photon Source (HEPS), China's flagship synchrotron radiation facility, is set to begin trial operations by the end of 2025, according to the project team. A synchrotron radiation light source is a source of electromagnetic radiation usually produced by a storage ring.

The High Energy Photon Source (HEPS), China's flagship synchrotron radiation facility, has officially launched its joint commissioning phase, marking its final construction stage. The Institute of High Energy Physics (IHEP) under the Chinese Academy of Sciences, the main HEPS developer, announced the new development at a parallel forum of the 2025 Zhongguancun Forum in Beijing on Thursday.
