Abstract

The Saga third-generation synchrotron light source (Saga-LS) is being constructed and is operated before the fall of 2004 in Tosu, Saga Prefecture in the northern part of Kyushu-island. The Saga-LS consists of a 262-MeV electron linac injector and an eight-hold symmetry 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 design. The circumference is 75.6 m and the emittance is 15 nm·rad at 1.4 GeV. Six insertion devices including a 7.5-T wiggler can be installed. The critical energies of synchrotron light from the bending magnet and the 7.5-T wiggler are 1.9 keV and 9.8 keV, respectively. The 262-MeV linac beam is used for injection and a 40-MeV linac beam branched off from the first accelerator tube (AT-1) is used for two-color infrared (IR) free electron laser (FEL) generation. We are planning 10 supply high brilliant photon beams covering wavelength range from 34 keV to 0.063 eV by using the Saga 1.4-GeV storage ring with six insertion devices including the 7.5-T wiggler and the IR- FEL facility.
