UVSOR是一种750 MeV的第二代同步加速器光源，被转换为UVSOR-II，它有八个直段，发射率为27 nm-rad。在不改变53.2 m周长的情况下修改了磁晶格。除弯曲磁铁外，所有磁铁及其射束导管均已更换。一个波荡器和一个超导摇摆器被两个新的真空波荡器取代。注射器的一些部件被更换和升级。重建了一些光束线。所有重建工程在2003年4月至6月的三个月内完成。7月，UVSOR‐II成功调试。对光束参数的一些初步测量表明，发射度的设计目标，27 nm-rad，很可能已经实现。正在进行梁真空处理。用户实验将于9月开始。
UVSOR, a 2nd generation synchrotron light source of 750 MeV, was converted to UVSOR‐II, which has eight straight sections and small emittance of 27 nm‐rad. The magnetic lattice was modified without changing the circumference of 53.2 m. All the magnets and their beam ducts except for the bending magnets were replaced. An undulator and a super‐conducting wiggler were replaced with two new in‐vacuum undulators. Some parts of the injector were replaced and upgraded. Some beam‐lines were reconstructed. All the reconstruction works were completed within three months, from April to June 2003. In July, UVSOR‐II was successfully commissioned. Some preliminary measurements on the beam parameters suggested that the design goal of the emittance, 27 nm‐rad, was likely achieved. Vacuum conditioning with beams are in progress. Users experiments will start in September.
