Present Status of the SAGA Light Source

Abstract

The SAGA Light Source (SAGA-LS) is an accelerator facility for the synchrotron radiation experiments. The accelerator complex consists of a 255 MeV linac and a 1.4 GeV storage ring. The commissioning of the accelerator began on August 2004. The SAGA-LS has been stably providing synchrotron radiation to users since it first stated user operation in February 2006. Currently three insertion devices (a planar undulator, an APPLE-II undulator and a 4 T superconducting wiggler) are in operaton. We present an overview of the accelerator performance with emphasis on the operational status and recent improvements and developments. In addition, recent studies on the superconducting wiggler, beam lifetime, laser Compton scattering, and the interaction between the electron beam and the crystal are also reported.
