Current Status of the SAGA Light Source Commissioning

The SAGA Light Source (SAGA-LS) is the third-generation synchrotron light source designed, constructed and operated by Saga Prefecture, the Japanese local government, for the promotion of scientific researches and industrial applications in Kyushu area. The SAGA-LS consists of a 250-MeV electron linac injector and a 1.4-GeV storage ring with eight double-bend (DB) cell and eight 2.93-m long straight sections. The DB cell structure with a distributed dispersion system was chosen to produce a compact and low cost ring of 75.6-m long circumference. The construction budget was 1.94 billion yen for the light source and 1.1 billion yen for the building. The machine installation started on September 29, 2003. The commissioning began on August 24, 2004. The first synchrotron light was observed on November 12. The commissioning goal of 1.4GeV-100mA was achieved on August 25, 2005. The SAGA-LS was opened for users in February 17, 2006
