Nanoterasu is the first facility in Japan designed to exclude most of the experimental hall from radiation-controlled areas by optimizing shielding and safety systems, so that Nanoterasu users who have completed radiation safety training are allowed to use the synchrotron radiation beamlines without the license of radiation workers. To protect these users from radiations generated by the 3 GeV electron linear accelerator and the electron storage ring with the maximum beam current of 413 mA, The safety interlock system is carefully designed for access control and radiation monitoring.
