Third Generation VUV/Soft X-ray Light Source Projects in Japan

Hiroyuki Hama
( Laboratory of Nuclear Science, Tohoku University, Japan) ABSTRACT Two 3rd generation light source projects for the VUV and SX region are presently under active consideration in Japan, and a decision is expected soon. The Tokyo University project is a 1.6 GeV maximum energy machine which features a minimum emittance lattice (less than 1 nm rad at 1 GeV) with two 27 m long straight sections. The optics has been specially optimised to expand the dynamic aperture. A 27 m undulator could provide very narrow bandwidth radiation, eliminating the need for a monochromater and so increasing the photon flux by a factor of 1000. The possibility of installing three undulators in a saw-tooth arrangement in the 27 m straight is also being considered. The Tohoku University project is a 1.8 GeV machine with emittance of 4.9 nm rad and is designed to have many insertions: the ring contains 14 straight sections of 5 m and two long straight sections with length of 15 m. A free-electron laser is being considered for one of the long straight sections. The status and main features of the projects will be described.
