**NanoTerasu Hosts Pre-Launch Showcase Ahead of Full-Scale 400 mA Operation — Special Demonstration Offering a First-Hand Experience of World-Class Synchrotron Light —**

2025-11-24

On November 24, the day before the start of full-scale operations, NanoTerasu opened to the media the process of increasing the storage ring current from 200 mA to 400 mA. During the demonstration at the public beamline BL06U, participants observed the moment of current ramp-up while an actual synchrotron radiation experiment was underway.
In July 2025, NanoTerasu achieved a major technological breakthrough, succeeding in stable 400 mA operation (Press Release, September 5, 2025: “Successful Early Achievement of Stable 400 mA Storage Ring Operation at NanoTerasu”). After confirming that no issues occurred during long-duration operation, the facility advanced the schedule by four months and is beginning user operations at 400 mA from November 25, 2025.
With this full-scale launch, synchrotron radiation with brightness 100 times higher than existing facilities in Japan—and among the highest in the world—will become fully accessible. This is expected to significantly accelerate cutting-edge research and development in next-generation devices, materials science, and life sciences, while further promoting innovation creation.
