KEK in Japan Completes World's First "Quantum Multi-Beam Utilization" Synchrotron Radiation Beamlines

On August 6, the High Energy Accelerator Research Organization (KEK) announced that the BL-11A and BL-11B beamlines at its Photon Factory (PF) synchrotron radiation experimental facility have been completed as the world's first "quantum multi-beam utilization" beamlines, enabling the simultaneous use of hard X-ray and soft X-ray beams.

According to reports, BL-11A and BL-11B were constructed in collaboration with the "Synchrotron Radiation Academic Infrastructure Network." This network consists of synchrotron radiation facilities operated by university joint-use organizations and joint-use/joint-research centers, positioned as scientific research and educational infrastructure.

The main feature of the new beamlines is the ability to simultaneously use hard X-ray and soft X-ray under the same experimental conditions, completing observation work that previously required separate measurements. Additionally, the facility supports a new measurement method: first using one type of X-ray to induce changes in a sample, then tracking those changes with the other type of X-ray. KEK anticipates that this technology will find applications in multiple research fields, including materials science and life sciences.

KEK plans to hold a press conference on August 20, 2026, at 15:00 at the Tsukuba campus and online, introducing the overview of the BL-11A and BL-11B beamlines and demonstrating experiments that simultaneously use both beams. The event will also include facility tours, with visits to the BL-11A and BL-11B beamlines. During the event, relevant researchers will provide explanations on beamline construction and application prospects, and participate in Q&A sessions.
