As China emerged on the global scientific stage it was keen to get in on the act. It therefore built the Beijing Synchrotron Radiation Facility (BSRF) – the country’s first such light source when it opened in 1991. Still operating, the BSRF is limited compared to other synchrotrons. After the BSRF, two more synchrotron sources were built in China. The HEPS will, however, be the country’s first fourth-generation synchrotron source – and one of only a handful of such facilities around the world. It will have even brighter beams using a still more advanced magnet array called a multi-bend achromat. The HEPS will be 1.3 km in circumference, have 60 – 70 beam lines with more than 90 experimental stations, and is expected to be completed by the end of 2025...read more.
