NanoTerasu Accelerator Opens to the Public

April 4, 2026, NanoTerasu held its public tour of its accelerator facilities.

The NanoTerasu accelerator is made up of a 110-meter-long linear accelerator, which accelerates electrons up to 3 GeV (3 billion electron volts), and a 349-meter-circumference storage ring, where electrons are stored and synchrotron radiation is generated.
By introducing a cutting-edge design that uses four bending magnets—twice the number found in conventional facilities—NanoTerasu achieves 100 times greater brightness and coherence than traditional systems.
A total of 29 participants, selected by lottery from a large pool of applicants, took part in the event: 14 in the morning session (including 5 junior high school, high school, and university students) and 15 in the afternoon session (including 5 junior high school, high school, and university students).

Following an introductory presentation by Masataka Kado, Leader of the Promotion and Public Relation Group, participants toured the state-of-the-art equipment that powers the linear accelerator, storage ring, and beamlines. The tour was guided by Takao Asaka, Technical Management of the Accelerator Group, Tomoyuki Takeuchi, Principal Engineers of the Beamline Group, and Takeshi Nakatani, Leader of the Network Data Management Group.

The event offered a rare behind-the-scenes look at one of the world’s most advanced synchrotron radiation facilities, generating excitement among all who attended.
