Lattice design for a future plan of UVSOR

Elham Salehi, ○Masahiro Katoh (UVSOR)

The lattice of UVSOR electron storage ring was upgraded twice. In 2003, the quadrupole magnets were replaced and rearranged to reduce the emittance and increase the number of the straight sections for undulators. In 2012, the bending magnets were replaced to reduce the emittance more. In this study, we explore a possibility to realize a diffraction limited light source in the VUV range. We investigate a new lattice for UVSOR which would give smaller emittance as keeping the present circumference. The latest results will be presented.
