Twenty years of operation of the SAGA Light Source

Abstract The SAGA Light Source (SAGA-LS) is a synchrotron radiation facility that consists of a 1.4 GeV storage ring with a 75.6m circumference and a 255MeV linear accelerator. Public use of the facility began in February 2006. Currently, 11 beamlines are operational. The annual user hours in the last five years were approximately 1650h, and the beam abortion rate was approximately 1.6% in FY2023. We plan to replace magnet power supply and the radiofrequency (RF) system in the storage ring for this fiscal year and the next one. In addition, a septum magnet, power supply of septum and kicker magnet, and steering power supply in the storage ring are being prepared for replacement.
